From the security announcement;
We have just released Go versions 1.22.4 and 1.21.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- archive/zip: mishandling of corrupt central directory record
The archive/zip package's handling of certain types of invalid zip files
differed from the behavior of most zip implementations. This misalignment
could be exploited to create an zip file with contents that vary depending
on the implementation reading the file. The archive/zip package now rejects
files containing these errors.
Thanks to Yufan You for reporting this issue.
This is CVE-2024-24789 and Go issue https://go.dev/issue/66869.
- net/netip: unexpected behavior from Is methods for IPv4-mapped IPv6 addresses
The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected
for IPv4-mapped IPv6 addresses, returning false for addresses which would
return true in their traditional IPv4 forms.
Thanks to Enze Wang of Alioth and Jianjun Chen of Zhongguancun Lab
for reporting this issue.
This is CVE-2024-24790 and Go issue https://go.dev/issue/67680.

We currently depend on the containerd platform-parsing to return typed
errdefs errors; the new containerd platforms module does not return such
errors, and documents that errors returned should not be used as sentinel
errors; c1438e911a/errors.go (L21-L30)
Let's type these errors ourselves, so that we don't depend on the error-types
returned by containerd, and consider that eny platform string that results in
an error is an invalid parameter.

If a node is promoted right after another node is demoted, there exists
the possibility of a race, by which the newly promoted manager attempts
to connect to the newly demoted manager for its initial Raft membership.
This connection fails, and the whole swarm Node object exits.
At this point, the daemon nodeRunner sees the exit and restarts the
Node.
However, if the address of the no-longer-manager is recorded in the
nodeRunner's config.joinAddr, the Node again attempts to connect to the
no-longer-manager, and crashes again. This repeats. The solution is to
remove the node entirely and rejoin the Swarm as a new node.
This change erases config.joinAddr from the restart of the nodeRunner,
if the node has previously become Ready. The node becoming Ready
indicates that at some point, it did successfully join the cluster, in
some fashion. If it has successfully joined the cluster, then Swarm has
its own persistent record of known manager addresses. If no joinAddr is
provided, then Swarm will choose from its persisted list of managers to
join, and will join a functioning manager.

/usr/sbin/runc is confined with "runc" profile[1] introduced in AppArmor
v4.0.0. This change breaks stopping of containers, because the profile
assigned to containers doesn't accept signals from the "runc" peer.
AppArmor >= v4.0.0 is currently part of Ubuntu Mantic (23.10) and later.
In the case of Docker, this regression is hidden by the fact that
dockerd itself sends SIGKILL to the running container after runc fails
to stop it. It is still a regression, because graceful shutdowns of
containers via "docker stop" are no longer possible, as SIGTERM from
runc is not delivered to them. This can be seen in logs from dockerd
when run with debug logging enabled and also from tracing signals with
killsnoop utility from bcc[2] (in bpfcc-tools package in Debian/Ubuntu):
Test commands:

This change extends the docker-default profile with rules that allow
receiving signals from processes that run confined with either runc or
crun profile (crun[4] is an alternative OCI runtime that's also confined
in AppArmor >= v4.0.0, see [1]). It is backward compatible because the
peer value is a regular expression (AARE) so the referenced profile
doesn't have to exist for this profile to successfully compile and load.
Note that the runc profile has an attachment to /usr/sbin/runc. This is
the path where the runc package in Debian/Ubuntu puts the binary. When
the docker-ce package is installed from the upstream repository[3], runc
is installed as part of the containerd.io package at /usr/bin/runc.
Therefore it's still running unconfined and has no issues sending
signals to containers.

This commit introduces a new integration test suite aimed at testing
networking features like inter-container communication, network
isolation, port mapping, etc... and how they interact with daemon-level
and network-level parameters.
So far, there's pretty much no tests making sure our networks are well
configured: 1. there're a few tests for port mapping, but they don't
cover all use cases ; 2. there're a few tests that check if a specific
iptables rule exist, but that doesn't prevent that specific iptables
rule to be wrong in the first place.
As we're planning to refactor how iptables rules are written, and change
some of them to fix known security issues, we need a way to test all
combinations of parameters. So far, this was done by hand, which is
particularly painful and time consuming. As such, this new test suite is
foundational to upcoming work.

With both rootless and live restore enabled, there's some race condition
which causes the container to be `Unmount`ed before the refcount is
restored.
This makes sure we don't underflow the refcount (uint64) when

The root cause of this race condition still needs to be investigated and

In de2447c, the creation of the 'lower' file was changed from using
os.Create to using ioutils.AtomicWriteFile, which ignores the system's
umask. This means that even though the requested permission in the
source code was always 0666, it was 0644 on systems with default
umask of 0022 prior to de2447c, so the move to AtomicFile potentially
increased the file's permissions.
This is not a security issue because the parent directory does not
allow writes into the file, but it can confuse security scanners on
Linux-based systems into giving false positives.

This syscall implements what was previously known as FUTEX_CMP_REQUEUE

destination.
This design explicitly allows requeueing between different types of
futex by having a different flags word per uaddr.

x86/shstk: Introduce map_shadow_stack syscall
When operating with shadow stacks enabled, the kernel will automatically
allocate shadow stacks for new threads, however in some cases userspace
will need additional shadow stacks. The main example of this is the
ucontext family of functions, which require userspace allocating and
pivoting to userspace managed stacks.
Unlike most other user memory permissions, shadow stacks need to be
provisioned with special data in order to be useful. They need to be setup
with a restore token so that userspace can pivot to them via the RSTORSSP
instruction. But, the security design of shadow stacks is that they
should not be written to except in limited circumstances. This presents a
problem for userspace, as to how userspace can provision this special
data, without allowing for the shadow stack to be generally writable.

fs: Add fchmodat2()
On the userspace side fchmodat(3) is implemented as a wrapper

There doesn't appear to be a good userspace workaround for this issue

[security] Go 1.21.5 and Go 1.20.12 are released
Hello gophers,
We have just released Go versions 1.21.5 and 1.20.12, minor point releases.
These minor releases include 3 security fixes following the security policy:
- net/http: limit chunked data overhead
A malicious HTTP sender can use chunk extensions to cause a receiver
reading from a request or response body to read many more bytes from
the network than are in the body.
A malicious HTTP client can further exploit this to cause a server to
automatically read a large amount of data (up to about 1GiB) when a
handler fails to read the entire body of a request.
Chunk extensions are a little-used HTTP feature which permit including
additional metadata in a request or response body sent using the chunked
encoding. The net/http chunked encoding reader discards this metadata.
A sender can exploit this by inserting a large metadata segment with
each byte transferred. The chunk reader now produces an error if the
ratio of real body to encoded bytes grows too small.
Thanks to Bartek Nowotarski for reporting this issue.
This is CVE-2023-39326 and Go issue https://go.dev/issue/64433.
- cmd/go: go get may unexpectedly fallback to insecure git
Using go get to fetch a module with the ".git" suffix may unexpectedly
fallback to the insecure "git://" protocol if the module is unavailable
via the secure "https://" and "git+ssh://" protocols, even if GOINSECURE
is not set for said module. This only affects users who are not using
the module proxy and are fetching modules directly (i.e. GOPROXY=off).
Thanks to David Leadbeater for reporting this issue.
This is CVE-2023-45285 and Go issue https://go.dev/issue/63845.
- path/filepath: retain trailing \ when cleaning paths like \\?\c:\
Go 1.20.11 and Go 1.21.4 inadvertently changed the definition of the
volume name in Windows paths starting with \\?\, resulting in
filepath.Clean(\\?\c:\) returning \\?\c: rather than \\?\c:\ (among
other effects). The previous behavior has been restored.

[security] Go 1.21.4 and Go 1.20.11 are released
Hello gophers,
We have just released Go versions 1.21.4 and 1.20.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- path/filepath: recognize `\??\` as a Root Local Device path prefix.
On Windows, a path beginning with `\??\` is a Root Local Device path equivalent
to a path beginning with `\\?\`. Paths with a `\??\` prefix may be used to
access arbitrary locations on the system. For example, the path `\??\c:\x`
is equivalent to the more common path c:\x.
The filepath package did not recognize paths with a `\??\` prefix as special.
Clean could convert a rooted path such as `\a\..\??\b` into
the root local device path `\??\b`. It will now convert this
path into `.\??\b`.
`IsAbs` did not report paths beginning with `\??\` as absolute.
It now does so.
VolumeName now reports the `\??\` prefix as a volume name.
`Join(`\`, `??`, `b`)` could convert a seemingly innocent
sequence of path elements into the root local device path
`\??\b`. It will now convert this to `\.\??\b`.
This is CVE-2023-45283 and https://go.dev/issue/63713.
- path/filepath: recognize device names with trailing spaces and superscripts
The `IsLocal` function did not correctly detect reserved names in some cases:
- reserved names followed by spaces, such as "COM1 ".
- "COM" or "LPT" followed by a superscript 1, 2, or 3.
`IsLocal` now correctly reports these names as non-local.
This is CVE-2023-45284 and https://go.dev/issue/63713.

This is the eleventh patch release in the 1.1.z release branch of runc.
It primarily fixes a few issues with runc's handling of containers that
are configured to join existing user namespaces, as well as improvements
to cgroupv2 support.
- Fix several issues with userns path handling.
- Support memory.peak and memory.swap.peak in cgroups v2.
Add swapOnlyUsage in MemoryStats. This field reports swap-only usage.
For cgroupv1, Usage and Failcnt are set by subtracting memory usage
from memory+swap usage. For cgroupv2, Usage, Limit, and MaxUsage
are set.
- build(deps): bump github.com/cyphar/filepath-securejoin.

This is the tenth (and most likely final) patch release in the 1.1.z
release branch of runc. It mainly fixes a few issues in cgroups, and a
umask-related issue in tmpcopyup.
- Add support for `hugetlb.<pagesize>.rsvd` limiting and accounting.
Fixes the issue of postgres failing when hugepage limits are set.
- Fixed permissions of a newly created directories to not depend on the value
of umask in tmpcopyup feature implementation.
- libcontainer: cgroup v1 GetStats now ignores missing `kmem.limit_in_bytes`
(fixes the compatibility with Linux kernel 6.1+).
- Fix a semi-arbitrary cgroup write bug when given a malicious hugetlb
configuration. This issue is not a security issue because it requires a
malicious config.json, which is outside of our threat model.

When the daemon process or the host running it is abruptly terminated,
the layer metadata file can become inconsistent on the file system.
Specifically, `link` and `lower` files may exist but be empty, leading
to overlay mounting errors during layer extraction, such as:
"failed to register layer: error creating overlay mount to <path>:
too many levels of symbolic links."
This commit introduces the use of `AtomicWriteFile` to ensure that the
layer metadata files contain correct data when they exist on the file system.

This fixes the same CVE as go1.21.3 and go1.20.10;
- net/http: rapid stream resets can cause excessive work
A malicious HTTP/2 client which rapidly creates requests and
immediately resets them can cause excessive server resource consumption.
While the total number of requests is bounded to the
http2.Server.MaxConcurrentStreams setting, resetting an in-progress
request allows the attacker to create a new request while the existing
one is still executing.
HTTP/2 servers now bound the number of simultaneously executing
handler goroutines to the stream concurrency limit. New requests
arriving when at the limit (which can only happen after the client
has reset an existing, in-flight request) will be queued until a
handler exits. If the request queue grows too large, the server
will terminate the connection.
This issue is also fixed in golang.org/x/net/http2 v0.17.0,
for users manually configuring HTTP/2.
The default stream concurrency limit is 250 streams (requests)
per HTTP/2 connection. This value may be adjusted using the
golang.org/x/net/http2 package; see the Server.MaxConcurrentStreams
setting and the ConfigureServer function.
This is CVE-2023-39325 and Go issue https://go.dev/issue/63417.

"//line" directives can be used to bypass the restrictions on "//go:cgo_"
directives, allowing blocked linker and compiler flags to be passed during

running "go build". The line directive requires the absolute path of the file in
which the directive lives, which makes exploting this issue significantly more
complex.

The ability to read these files may offer a power-based sidechannel
attack against any workloads running on the same kernel.
This was originally [CVE-2020-8694][1], which was fixed in
[949dd0104c496fa7c14991a23c03c62e44637e71][2] by restricting read access
to root. However, since many containers run as root, this is not
sufficient for our use case.
While untrusted code should ideally never be run, we can add some
defense in depth here by masking out the device class by default.
[Other mechanisms][3] to access this hardware exist, but they should not
be accessible to a container due to other safeguards in the
kernel/container stack (e.g. capabilities, perf paranoia).

On startup all local volumes were unmounted as a cleanup mechanism for
the non-clean exit of the last engine process.
This caused live-restored volumes that used special volume opt mount
flags to be broken. While the refcount was restored, the _data directory
was just unmounted, so all new containers mounting this volume would
just have the access to the empty _data directory instead of the real
volume.
With this patch, the mountpoint isn't unmounted. Instead, if the volume
is already mounted, just mark it as mounted, so the next time Mount is
called only the ref count is incremented, but no second attempt to mount
it is performed.

Many of the fields in LinuxResources struct are pointers to scalars for
some reason, presumably to differentiate between set-to-zero and unset
when unmarshaling from JSON, despite zero being outside the acceptable
range for the corresponding kernel tunables. When creating the OCI spec
for a container, the daemon sets the container's OCI spec CPUShares and
BlkioWeight parameters to zero when the corresponding Docker container
configuration values are zero, signifying unset, despite the minimum
acceptable value for CPUShares being two, and BlkioWeight ten. This has
gone unnoticed as runC does not distingiush set-to-zero from unset as it
also uses zero internally to represent unset for those fields. However,
kata-containers v3.2.0-alpha.3 tries to apply the explicit-zero resource
parameters to the container, exactly as instructed, and fails loudly.
The OCI runtime-spec is silent on how the runtime should handle the case
when those parameters are explicitly set to out-of-range values and
kata's behaviour is not unreasonable, so the daemon must therefore be in
the wrong.
Translate unset values in the Docker container's resources HostConfig to
omit the corresponding fields in the container's OCI spec when starting
and updating a container in order to maximize compatibility with
runtimes.

Go 1.15.7 contained a security fix for CVE-2021-3115, which allowed arbitrary
code to be executed at build time when using cgo on Windows.
This issue was not limited to the go command itself, and could also affect binaries
that use `os.Command`, `os.LookPath`, etc.
From the related blogpost (https://blog.golang.org/path-security):
> Are your own programs affected?
>
> If you use exec.LookPath or exec.Command in your own programs, you only need to
> be concerned if you (or your users) run your program in a directory with untrusted
> contents. If so, then a subprocess could be started using an executable from dot
> instead of from a system directory. (Again, using an executable from dot happens
> always on Windows and only with uncommon PATH settings on Unix.)
>
> If you are concerned, then we’ve published the more restricted variant of os/exec
> as golang.org/x/sys/execabs. You can use it in your program by simply replacing
At time of the go1.15 release, the Go team considered changing the behavior of
`os.LookPath()` and `exec.LookPath()` to be a breaking change, and made the
behavior "opt-in" by providing the `golang.org/x/sys/execabs` package as a
replacement.
However, for the go1.19 release, this changed, and the default behavior of
`os.LookPath()` and `exec.LookPath()` was changed. From the release notes:
https://go.dev/doc/go1.19#os-exec-path
> Command and LookPath no longer allow results from a PATH search to be found
> relative to the current directory. This removes a common source of security
> problems but may also break existing programs that depend on using, say,
> exec.Command("prog") to run a binary named prog (or, on Windows, prog.exe)
> in the current directory. See the os/exec package documentation for information
> about how best to update such programs.
>
> On Windows, Command and LookPath now respect the NoDefaultCurrentDirectoryInExePath
> environment variable, making it possible to disable the default implicit search
> of “.” in PATH lookups on Windows systems.
A result of this change was that registering the daemon as a Windows service
no longer worked when done from within the directory of the binary itself:
C:\> cd "Program Files\Docker\Docker\resources"
C:\Program Files\Docker\Docker\resources> dockerd --register-service
exec: "dockerd": cannot run executable found relative to current directory
Note that using an absolute path would work around the issue:
C:\Program Files\Docker\Docker>resources\dockerd.exe --register-service
This patch changes `registerService()` to use `os.Executable()`, instead of
depending on `os.Args[0]` and `exec.LookPath()` for resolving the absolute
path of the binary.

From the mailing list announcement:
[security] Go 1.20.7 and Go 1.19.12 are released
Hello gophers,
We have just released Go versions 1.20.7 and 1.19.12, minor point releases.
These minor releases include 1 security fixes following the security policy:
- crypto/tls: restrict RSA keys in certificates to <= 8192 bits
Extremely large RSA keys in certificate chains can cause a client/server
to expend significant CPU time verifying signatures. Limit this by
restricting the size of RSA keys transmitted during handshakes to <=
8192 bits.
Based on a survey of publicly trusted RSA keys, there are currently only
three certificates in circulation with keys larger than this, and all
three appear to be test certificates that are not actively deployed. It
is possible there are larger keys in use in private PKIs, but we target
the web PKI, so causing breakage here in the interests of increasing the
default safety of users of crypto/tls seems reasonable.
Thanks to Mateusz Poliwczak for reporting this issue.

I noticed this was always being skipped because of race conditions
checking the logs.
This change adds a log scanner which will look through the logs line by
line rather than allocating a big buffer.
Additionally it adds a `poll.Check` which we can use to actually wait
for the desired log entry.

For local communications (npipe://, unix://), the hostname is not used,
but we need valid and meaningful hostname.
The current code used the client's `addr` as hostname in some cases, which
could contain the path for the unix-socket (`/var/run/docker.sock`), which
gets rejected by go1.20.6 and go1.19.11 because of a security fix for
[CVE-2023-29406 ][1], which was implemented in https://go.dev/issue/60374.
Prior versions go Go would clean the host header, and strip slashes in the
process, but go1.20.6 and go1.19.11 no longer do, and reject the host
header.
This patch introduces a `DummyHost` const, and uses this dummy host for
cases where we don't need an actual hostname.

Multiple daemons starting/running concurrently can collide with each
other when editing iptables rules. Most integration tests which opt into
parallelism and start daemons work around this problem by starting the
daemon with the --iptables=false option. However, some of the tests
neglect to pass the option when starting or restarting the daemon,
resulting in those tests being flaky.
Audit the integration tests which call t.Parallel() and (*Daemon).Stop()
and add --iptables=false arguments where needed.

TestClientWithRequestTimeout has been observed to flake in CI. The
timing in the test is quite tight, only giving the client a 10ms window
to time out, which could potentially be missed if the host is under
load and the goroutine scheduling is unlucky. Give the client a full
five seconds of grace to time out before failing the test.

Linux 6.2 and up (commit [f1f1f2569901ec5b9d425f2e91c09a0e320768f3][1])

Commit 8d56108ffb moved this function from
the generic (no build-tags) fileutils.go to a unix file, adding "freebsd"
to the build-tags.
This likely was a wrong assumption (as other files had freebsd build-tags).
FreeBSD's procfs does not mention `/proc/<pid>/fd` in the manpage, and
we don't test FreeBSD in CI, so let's drop it, and make this a Linux-only
file.
While updating also dropping the import-tag, as we're planning to move
this file internal to the daemon.

go1.20.5 (released 2023-06-06) includes four security fixes to the cmd/go and
runtime packages, as well as bug fixes to the compiler, the go command, the
runtime, and the crypto/rsa, net, and os packages. See the Go 1.20.5 milestone
on our issue tracker for details:

full diff: https://github.com/golang/go/compare/go1.20.4...go1.20.5
These minor releases include 3 security fixes following the security policy:
- cmd/go: cgo code injection
The go command may generate unexpected code at build time when using cgo. This
may result in unexpected behavior when running a go program which uses cgo.
This may occur when running an untrusted module which contains directories with
newline characters in their names. Modules which are retrieved using the go command,
i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e.
GO111MODULE=off, may be affected).
Thanks to Juho Nurminen of Mattermost for reporting this issue.
This is CVE-2023-29402 and Go issue https://go.dev/issue/60167.
- runtime: unexpected behavior of setuid/setgid binaries
The Go runtime didn't act any differently when a binary had the setuid/setgid
bit set. On Unix platforms, if a setuid/setgid binary was executed with standard
I/O file descriptors closed, opening any files could result in unexpected
content being read/written with elevated prilieges. Similarly if a setuid/setgid
program was terminated, either via panic or signal, it could leak the contents
of its registers.
Thanks to Vincent Dehors from Synacktiv for reporting this issue.
This is CVE-2023-29403 and Go issue https://go.dev/issue/60272.
- cmd/go: improper sanitization of LDFLAGS
The go command may execute arbitrary code at build time when using cgo. This may
occur when running "go get" on a malicious module, or when running any other
command which builds untrusted code. This is can by triggered by linker flags,
specified via a "#cgo LDFLAGS" directive.
Thanks to Juho Nurminen of Mattermost for reporting this issue.

go1.20.3 (released 2023-04-04) includes security fixes to the go/parser,
html/template, mime/multipart, net/http, and net/textproto packages, as well
as bug fixes to the compiler, the linker, the runtime, and the time package.

https://github.com/golang/go/issues?q=milestone%3AGo1.20.3+label%3ACherryPickApproved
full diff: https://github.com/golang/go/compare/go1.20.2...go1.20.3
Further details from the announcement on the mailing list:
We have just released Go versions 1.20.3 and 1.19.8, minor point releases.
These minor releases include 4 security fixes following the security policy:
- go/parser: infinite loop in parsing
Calling any of the Parse functions on Go source code which contains `//line`
directives with very large line numbers can cause an infinite loop due to
integer overflow.
Thanks to Philippe Antoine (Catena cyber) for reporting this issue.
This is CVE-2023-24537 and Go issue https://go.dev/issue/59180.
- html/template: backticks not treated as string delimiters
Templates did not properly consider backticks (`) as Javascript string
delimiters, and as such did not escape them as expected. Backticks are
used, since ES6, for JS template literals. If a template contained a Go
template action within a Javascript template literal, the contents of the
action could be used to terminate the literal, injecting arbitrary Javascript
code into the Go template.
As ES6 template literals are rather complex, and themselves can do string
interpolation, we've decided to simply disallow Go template actions from being
used inside of them (e.g. "var a = {{.}}"), since there is no obviously safe
way to allow this behavior. This takes the same approach as
github.com/google/safehtml. Template.Parse will now return an Error when it
encounters templates like this, with a currently unexported ErrorCode with a
value of 12. This ErrorCode will be exported in the next major release.
Users who rely on this behavior can re-enable it using the GODEBUG flag
jstmpllitinterp=1, with the caveat that backticks will now be escaped. This
should be used with caution.
Thanks to Sohom Datta, Manipal Institute of Technology, for reporting this issue.
This is CVE-2023-24538 and Go issue https://go.dev/issue/59234.
- net/http, net/textproto: denial of service from excessive memory allocation
HTTP and MIME header parsing could allocate large amounts of memory, even when
parsing small inputs.
Certain unusual patterns of input data could cause the common function used to
parse HTTP and MIME headers to allocate substantially more memory than
required to hold the parsed headers. An attacker can exploit this behavior to
cause an HTTP server to allocate large amounts of memory from a small request,
potentially leading to memory exhaustion and a denial of service.
Header parsing now correctly allocates only the memory required to hold parsed
headers.
Thanks to Jakob Ackermann (@das7pad) for discovering this issue.
This is CVE-2023-24534 and Go issue https://go.dev/issue/58975.
- net/http, net/textproto, mime/multipart: denial of service from excessive resource consumption
Multipart form parsing can consume large amounts of CPU and memory when
processing form inputs containing very large numbers of parts. This stems from
several causes:
mime/multipart.Reader.ReadForm limits the total memory a parsed multipart form
can consume. ReadForm could undercount the amount of memory consumed, leading
it to accept larger inputs than intended. Limiting total memory does not
account for increased pressure on the garbage collector from large numbers of
small allocations in forms with many parts. ReadForm could allocate a large
number of short-lived buffers, further increasing pressure on the garbage
collector. The combination of these factors can permit an attacker to cause an
program that parses multipart forms to consume large amounts of CPU and
memory, potentially resulting in a denial of service. This affects programs
that use mime/multipart.Reader.ReadForm, as well as form parsing in the
net/http package with the Request methods FormFile, FormValue,
ParseMultipartForm, and PostFormValue.
ReadForm now does a better job of estimating the memory consumption of parsed
forms, and performs many fewer short-lived allocations.
In addition, mime/multipart.Reader now imposes the following limits on the
size of parsed forms:
Forms parsed with ReadForm may contain no more than 1000 parts. This limit may
be adjusted with the environment variable GODEBUG=multipartmaxparts=. Form
parts parsed with NextPart and NextRawPart may contain no more than 10,000
header fields. In addition, forms parsed with ReadForm may contain no more
than 10,000 header fields across all parts. This limit may be adjusted with
the environment variable GODEBUG=multipartmaxheaders=.
Thanks to Jakob Ackermann for discovering this issue.

daemon.generateNewName() already reserves the generated name, but its name

These minor releases include 3 security fixes following the security policy:
- cmd/go: cgo code injection
The go command may generate unexpected code at build time when using cgo. This
may result in unexpected behavior when running a go program which uses cgo.
This may occur when running an untrusted module which contains directories with
newline characters in their names. Modules which are retrieved using the go command,
i.e. via "go get", are not affected (modules retrieved using GOPATH-mode, i.e.
GO111MODULE=off, may be affected).
Thanks to Juho Nurminen of Mattermost for reporting this issue.
This is CVE-2023-29402 and Go issue https://go.dev/issue/60167.
- runtime: unexpected behavior of setuid/setgid binaries
The Go runtime didn't act any differently when a binary had the setuid/setgid
bit set. On Unix platforms, if a setuid/setgid binary was executed with standard
I/O file descriptors closed, opening any files could result in unexpected
content being read/written with elevated prilieges. Similarly if a setuid/setgid
program was terminated, either via panic or signal, it could leak the contents
of its registers.
Thanks to Vincent Dehors from Synacktiv for reporting this issue.
This is CVE-2023-29403 and Go issue https://go.dev/issue/60272.
- cmd/go: improper sanitization of LDFLAGS
The go command may execute arbitrary code at build time when using cgo. This may
occur when running "go get" on a malicious module, or when running any other
command which builds untrusted code. This is can by triggered by linker flags,
specified via a "#cgo LDFLAGS" directive.

While the VXLAN interface and the iptables rules to mark outgoing VXLAN
packets for encryption are configured to use the Swarm data path port,
the XFRM policies for actually applying the encryption are hardcoded to
match packets with destination port 4789/udp. Consequently, encrypted
overlay networks do not pass traffic when the Swarm is configured with
any other data path port: encryption is not applied to the outgoing
VXLAN packets and the destination host drops the received cleartext
packets. Use the configured data path port instead of hardcoding port
4789 in the XFRM policies.

Starting with go1.19, the Go runtime on Windows now supports the `netgo` build-
flag to use a native Go DNS resolver. Prior to that version, the build-flag
only had an effect on non-Windows platforms. When using the `netgo` build-flag,
the Windows's host resolver is not used, and as a result, custom entries in
`etc/hosts` are ignored, which is a change in behavior from binaries compiled
with older versions of the Go runtime.
From the go1.19 release notes: https://go.dev/doc/go1.19#net
> Resolver.PreferGo is now implemented on Windows and Plan 9. It previously
> only worked on Unix platforms. Combined with Dialer.Resolver and Resolver.Dial,
> it's now possible to write portable programs and be in control of all DNS name
> lookups when dialing.
>
> The net package now has initial support for the netgo build tag on Windows.
> When used, the package uses the Go DNS client (as used by Resolver.PreferGo)
> instead of asking Windows for DNS results. The upstream DNS server it discovers

> however.
Our Windows binaries are compiled with the "static" (`make/binary-daemon`)
script, which has the `netgo` option set by default. This patch unsets the
`netgo` option when cross-compiling for Windows.

This is the seventh patch release in the 1.1.z release of runc, and is
the last planned release of the 1.1.z series. It contains a fix for
cgroup device rules with systemd when handling device rules for devices
that don't exist (though for devices whose drivers don't correctly
register themselves in the kernel -- such as the NVIDIA devices -- the
full fix only works with systemd v240+).
- When used with systemd v240+, systemd cgroup drivers no longer skip
DeviceAllow rules if the device does not exist (a regression introduced
in runc 1.1.3). This fix also reverts the workaround added in runc 1.1.5,
removing an extra warning emitted by runc run/start.
- The source code now has a new file, runc.keyring, which contains the keys
used to sign runc releases.

This is the sixth patch release in the 1.1.z series of runc, which fixes
a series of cgroup-related issues.
Note that this release can no longer be built from sources using Go
1.16. Using a latest maintained Go 1.20.x or Go 1.19.x release is
recommended. Go 1.17 can still be used.
- systemd cgroup v1 and v2 drivers were deliberately ignoring UnitExist error
from systemd while trying to create a systemd unit, which in some scenarios
may result in a container not being added to the proper systemd unit and
cgroup.
- systemd cgroup v2 driver was incorrectly translating cpuset range from spec's
resources.cpu.cpus to systemd unit property (AllowedCPUs) in case of more
than 8 CPUs, resulting in the wrong AllowedCPUs setting.
- systemd cgroup v1 driver was prefixing container's cgroup path with the path
of PID 1 cgroup, resulting in inability to place PID 1 in a non-root cgroup.
- runc run/start may return "permission denied" error when starting a rootless
container when the file to be executed does not have executable bit set for
the user, not taking the CAP_DAC_OVERRIDE capability into account. This is
a regression in runc 1.1.4, as well as in Go 1.20 and 1.20.1
- cgroup v1 drivers are now aware of misc controller.

* CVE-2023-25809 is a vulnerability involving rootless containers where
(under specific configurations), the container would have write access
to the /sys/fs/cgroup/user.slice/... cgroup hierarchy. No other
hierarchies on the host were affected. This vulnerability was
discovered by Akihiro Suda.

In addition, the following other fixes are included in this release:
* Fix the inability to use `/dev/null` when inside a container.
* Fix changing the ownership of host's `/dev/null` caused by fd redirection
(a regression in 1.1.1).
* Fix rare runc exec/enter unshare error on older kernels, including
CentOS < 7.7.

The (*network).ipamRelease function nils out the network's IPAM info
fields, putting the network struct into an inconsistent state. The
network-restore startup code panics if it tries to restore a network
from a struct which has fewer IPAM config entries than IPAM info
entries. Therefore (*network).delete contains a critical section: by
persisting the network to the store after ipamRelease(), the datastore
will contain an inconsistent network until the deletion operation
completes and finishes deleting the network from the datastore. If for
any reason the deletion operation is interrupted between ipamRelease()
and deleteFromStore(), the daemon will crash on startup when it tries to
restore the network.
Updating the datastore after releasing the network's IPAM pools may have
served a purpose in the past, when a global datastore was used for
intra-cluster communication and the IPAM allocator had persistent global
state, but nowadays there is no global datastore and the IPAM allocator
has no persistent state whatsoever. Remove the vestigial datastore
update as it is no longer necessary and only serves to cause problems.
If the network deletion is interrupted before the network is deleted
from the datastore, the deletion will resume during the next daemon
startup, including releasing the IPAM pools.

go1.19.8 (released 2023-04-04) includes security fixes to the go/parser,
html/template, mime/multipart, net/http, and net/textproto packages, as well as
bug fixes to the linker, the runtime, and the time package. See the Go 1.19.8
milestone on our issue tracker for details:

full diff: https://github.com/golang/go/compare/go1.19.7...go1.19.8
Further details from the announcement on the mailing list:
We have just released Go versions 1.20.3 and 1.19.8, minor point releases.
These minor releases include 4 security fixes following the security policy:
- go/parser: infinite loop in parsing
Calling any of the Parse functions on Go source code which contains `//line`
directives with very large line numbers can cause an infinite loop due to
integer overflow.
Thanks to Philippe Antoine (Catena cyber) for reporting this issue.
This is CVE-2023-24537 and Go issue https://go.dev/issue/59180.
- html/template: backticks not treated as string delimiters
Templates did not properly consider backticks (`) as Javascript string
delimiters, and as such did not escape them as expected. Backticks are
used, since ES6, for JS template literals. If a template contained a Go
template action within a Javascript template literal, the contents of the
action could be used to terminate the literal, injecting arbitrary Javascript
code into the Go template.
As ES6 template literals are rather complex, and themselves can do string
interpolation, we've decided to simply disallow Go template actions from being
used inside of them (e.g. "var a = {{.}}"), since there is no obviously safe
way to allow this behavior. This takes the same approach as
github.com/google/safehtml. Template.Parse will now return an Error when it
encounters templates like this, with a currently unexported ErrorCode with a
value of 12. This ErrorCode will be exported in the next major release.
Users who rely on this behavior can re-enable it using the GODEBUG flag
jstmpllitinterp=1, with the caveat that backticks will now be escaped. This
should be used with caution.
Thanks to Sohom Datta, Manipal Institute of Technology, for reporting this issue.
This is CVE-2023-24538 and Go issue https://go.dev/issue/59234.
- net/http, net/textproto: denial of service from excessive memory allocation
HTTP and MIME header parsing could allocate large amounts of memory, even when
parsing small inputs.
Certain unusual patterns of input data could cause the common function used to
parse HTTP and MIME headers to allocate substantially more memory than
required to hold the parsed headers. An attacker can exploit this behavior to
cause an HTTP server to allocate large amounts of memory from a small request,
potentially leading to memory exhaustion and a denial of service.
Header parsing now correctly allocates only the memory required to hold parsed
headers.
Thanks to Jakob Ackermann (@das7pad) for discovering this issue.
This is CVE-2023-24534 and Go issue https://go.dev/issue/58975.
- net/http, net/textproto, mime/multipart: denial of service from excessive resource consumption
Multipart form parsing can consume large amounts of CPU and memory when
processing form inputs containing very large numbers of parts. This stems from
several causes:
mime/multipart.Reader.ReadForm limits the total memory a parsed multipart form
can consume. ReadForm could undercount the amount of memory consumed, leading
it to accept larger inputs than intended. Limiting total memory does not
account for increased pressure on the garbage collector from large numbers of
small allocations in forms with many parts. ReadForm could allocate a large
number of short-lived buffers, further increasing pressure on the garbage
collector. The combination of these factors can permit an attacker to cause an
program that parses multipart forms to consume large amounts of CPU and
memory, potentially resulting in a denial of service. This affects programs
that use mime/multipart.Reader.ReadForm, as well as form parsing in the
net/http package with the Request methods FormFile, FormValue,
ParseMultipartForm, and PostFormValue.
ReadForm now does a better job of estimating the memory consumption of parsed
forms, and performs many fewer short-lived allocations.
In addition, mime/multipart.Reader now imposes the following limits on the
size of parsed forms:
Forms parsed with ReadForm may contain no more than 1000 parts. This limit may
be adjusted with the environment variable GODEBUG=multipartmaxparts=. Form
parts parsed with NextPart and NextRawPart may contain no more than 10,000
header fields. In addition, forms parsed with ReadForm may contain no more
than 10,000 header fields across all parts. This limit may be adjusted with
the environment variable GODEBUG=multipartmaxheaders=.
Thanks to Jakob Ackermann for discovering this issue.
This is CVE-2023-24536 and Go issue https://go.dev/issue/59153.

commit 59118bff50 made this a direct
dependency (previously it was indirect). That commit was part of an
advisory, and didn't run the vendor validation check because of that.
This patch fixes the vendor.mod to unblock CI in this branch.

The netutils.ElectInterfaceAddresses function is only used in one place
outside of tests: in the daemon, to configure the default bridge
network. The function is also messy to reason about as it references the
shared mutable state of ipamutils.PredefinedLocalScopeDefaultNetworks.
It uses the list of predefined default networks to always return an IPv4
address even if the named interface does not exist or does not have any
IPv4 addresses. This list happens to be the same as the one used to
initialize the address pool of the 'builtin' IPAM driver, though that is
far from obvious. (Start with "./libnetwork".initIPAMDrivers and trace
the dataflow of the addressPool value. Surprise! Global state is being
mutated using the value of other global mutable state.)
The daemon does not need the fallback behaviour of
ElectInterfaceAddresses. In fact, the daemon does not have to configure
an address pool for the network at all! libnetwork will acquire one of
the available address ranges from the network's IPAM driver when the
preferred-pool configuration is unset. It will do so using the same list
of address ranges and the exact same logic
(netutils.FindAvailableNetworks) as ElectInterfaceAddresses. So unless
the daemon needs to force the network to use a specific address range
because the bridge interface already exists, it can leave the details
up to libnetwork.

release notes: https://github.com/opencontainers/runc/releases/tag/v1.1.5
diff: https://github.com/opencontainers/runc/compare/v1.1.4...v1.1.5
This is the fifth patch release in the 1.1.z series of runc, which fixes
three CVEs found in runc.
* CVE-2023-25809 is a vulnerability involving rootless containers where
(under specific configurations), the container would have write access
to the /sys/fs/cgroup/user.slice/... cgroup hierarchy. No other
hierarchies on the host were affected. This vulnerability was
discovered by Akihiro Suda.
<https://github.com/opencontainers/runc/security/advisories/GHSA-m8cg-xc2p-r3fc>
* CVE-2023-27561 was a regression which effectively re-introduced
CVE-2019-19921. This bug was present from v1.0.0-rc95 to v1.1.4. This
regression was discovered by @Beuc.
<https://github.com/advisories/GHSA-vpvm-3wq2-2wvm>
* CVE-2023-28642 is a variant of CVE-2023-27561 and was fixed by the same
patch. This variant of the above vulnerability was reported by Lei
Wang.
<https://github.com/opencontainers/runc/security/advisories/GHSA-g2j6-57v7-gm8c>
In addition, the following other fixes are included in this release:
* Fix the inability to use `/dev/null` when inside a container.
* Fix changing the ownership of host's `/dev/null` caused by fd redirection
(a regression in 1.1.1).
* Fix rare runc exec/enter unshare error on older kernels, including
CentOS < 7.7.
* nsexec: Check for errors in `write_log()`.

FirewallD creates the root INPUT chain with a default-accept policy and
a terminal rule which rejects all packets not accepted by any prior
rule. Any subsequent rules appended to the chain are therefore inert.
The administrator would have to open the VXLAN UDP port to make overlay
networks work at all, which would result in all VXLAN traffic being
accepted and defeating our attempts to enforce encryption on encrypted
overlay networks.
Insert the rule to drop unencrypted VXLAN packets tagged for encrypted
overlay networks at the top of the INPUT chain so that enforcement of
mandatory encryption takes precedence over any accept rules configured
by the administrator. Continue to append the accept rule to the bottom
of the chain so as not to override any administrator-configured drop
rules.

Some newer distros such as RHEL 9 have stopped making the xt_u32 kernel
module available with the kernels they ship. They do ship the xt_bpf
kernel module, which can do everything xt_u32 can and more. Add an
alternative implementation of the iptables match rule which uses xt_bpf
to implement exactly the same logic as the u32 filter using a BPF
program. Try programming the BPF-powered rules as a fallback when
programming the u32-powered rules fails.

The iptables rule clause used to match on the VNI of VXLAN datagrams
looks like line noise to the uninitiated. It doesn't help that the
expression is repeated twice and neither copy has any commentary.
DRY out the rule builder to a common function, and document what the
rule does and how it works.

The iptables rules which make encryption mandatory on an encrypted
overlay network are only programmed once there is a second node
participating in the network. This leaves single-node encrypted overlay
networks vulnerable to packet injection. Furthermore, failure to program
the rules is not treated as a fatal error.
Program the iptables rules to make encryption mandatory before creating
the VXLAN link to guarantee that there is no window of time where
incoming cleartext VXLAN packets for the network would be accepted, or
outgoing cleartext packets be transmitted. Only create the VXLAN link if
programming the rules succeeds to ensure that it fails closed.

The overlay-network encryption code is woefully under-documented, which
is especially problematic as it operates on under-documented kernel
interfaces. Document what I have puzzled out of the implementation for
the benefit of the next poor soul to touch this code.
