This is the fifth patch release in the 1.2.z series of runc. It primarily fixes
an issue caused by an upstream systemd bug.
* There was a regression in systemd v230 which made the way we define
device rule restrictions require a systemctl daemon-reload for our
transient units. This caused issues for workloads using NVIDIA GPUs.
Workaround the upstream regression by re-arranging how the unit properties
are defined.
* Dependency github.com/cyphar/filepath-securejoin is updated to v0.4.1,
to allow projects that vendor runc to bump it as well.
* CI: fixed criu-dev compilation.
* Dependency golang.org/x/net is updated to 0.33.0.

This minor release include 1 security fix following the security policy:
- crypto/elliptic: timing sidechannel for P-256 on ppc64le
Due to the usage of a variable time instruction in the assembly implementation
of an internal function, a small number of bits of secret scalars are leaked on
the ppc64le architecture. Due to the way this function is used, we do not
believe this leakage is enough to allow recovery of the private key when P-256
is used in any well known protocols.
This is CVE-2025-22866 and Go issue https://go.dev/issue/71383.

When a NAT-based port mapping is created, the daemon adds a DNAT rule in
nat-DOCKER to replace the dest addr with the container IP. However, the
daemon never sets up rules to filter packets destined directly to the
container port. This allows a rogue neighbor (ie. a host that shares a
L2 segment with the host) to send packets directly to the container on
its container-side exposed port.
For instance, if container port 5000 is mapped to host port 6000, a
neighbor could send packets directly to the container on its port 5000.
Since nat-DOCKER mangles the dest addr, and the nat table forbids DROP
rules, this change adds a new rule in the raw-PREROUTING chain to filter
ingress connections targeting the container's IP address.
This filtering is only done when gw_mode=nat. For the unprotected
variant, no filtering is done.

Hello gophers,
We have just released Go versions 1.23.5 and 1.22.11, minor point releases.
These minor releases include 2 security fixes following the security policy:
- crypto/x509: usage of IPv6 zone IDs can bypass URI name constraints
A certificate with a URI which has a IPv6 address with a zone ID may
incorrectly satisfy a URI name constraint that applies to the certificate
chain.
Certificates containing URIs are not permitted in the web PKI, so this
only affects users of private PKIs which make use of URIs.
Thanks to Juho Forsén of Mattermost for reporting this issue.
This is CVE-2024-45341 and Go issue https://go.dev/issue/71156.
- net/http: sensitive headers incorrectly sent after cross-domain redirect
The HTTP client drops sensitive headers after following a cross-domain redirect.
For example, a request to a.com/ containing an Authorization header which is
redirected to b.com/ will not send that header to b.com.
In the event that the client received a subsequent same-domain redirect, however,
the sensitive headers would be restored. For example, a chain of redirects from
a.com/, to b.com/1, and finally to b.com/2 would incorrectly send the Authorization
header to b.com/2.
Thanks to Kyle Seely for reporting this issue.
This is CVE-2024-45336 and Go issue https://go.dev/issue/70530.

When a NAT-based port mapping is created with a HostIP specified, we
insert a DNAT rule in nat-DOCKER to replace the dest addr with the
container IP. Then, in filter chains, we allow access to the container
port for any packet not coming from the container's network itself (if
hairpinning is disabled), nor from another host bridge.
However we don't set any rule that prevents a rogue neighbor that shares
a L2 segment with the host, but not the one where the port binding is
expected to be published, from sending packets destined to that HostIP.
For instance, if a port binding is created with HostIP == '127.0.0.1',
this port should not be accessible from anything but the lo interface.
That's currently not the case and this provides a false sense of
security.
Since nat-DOCKER mangles the dest addr, and the nat table rejects DROP
rules, this change adds rules into raw-PREROUTING to filter ingress
packets destined to mapped ports based on the input interface, the dest
addr and the dest port.
Interfaces are dynamically resolved when packets hit the host, thanks
to iptables' addrtype extension. This extension does a fib lookup of the
dest addr and checks that it's associated with the interface reached.
Also, when a proxy-based port mapping is created, as is the case when an
IPv6 HostIP is specified but the container is only IPv4-capable, we
don't set any sort of filtering. So the same issue might happen. The
reason is a bit different - in that case, that's just how the kernel
works. But, in order to stay consistent with NAT-based mappings, these
rules are also applied.
The env var `DOCKER_DISABLE_INPUT_IFACE_FILTERING` can be set to any
true-ish value to globally disable this behavior.

This is the fourth patch release of the 1.2.z release branch of runc. It
includes a fix for a regression introduced in 1.2.0 related to the
default device list.
- Re-add tun/tap devices to built-in allowed devices lists.
In runc 1.2.0 we removed these devices from the default allow-list
(which were added seemingly by accident early in Docker's history) as
a precaution in order to try to reduce the attack surface of device
inodes available to most containers. At the time we thought
that the vast majority of users using tun/tap would already be
specifying what devices they need (such as by using --device with
Docker/Podman) as opposed to doing the mknod manually, and thus
there would've been no user-visible change.
Unfortunately, it seems that this regressed a noticeable number of
users (and not all higher-level tools provide easy ways to specify
devices to allow) and so this change needed to be reverted. Users
that do not need these devices are recommended to explicitly disable
them by adding deny rules in their container configuration.

This is the third patch release of the 1.2.z release branch of runc. It
primarily fixes some minor regressions introduced in 1.2.0.
- Fixed a regression in use of securejoin.MkdirAll, where multiple
runc processes racing to create the same mountpoint in a shared rootfs
would result in spurious EEXIST errors. In particular, this regression
caused issues with BuildKit.
- Fixed a regression in eBPF support for pre-5.6 kernels after upgrading
Cilium's eBPF library version to 0.16 in runc.

Breaking changes and deprecations are included below;
Breaking changes:
Several aspects of how mount options work has been adjusted in a way that
could theoretically break users that have very strange mount option strings.
This was necessary to fix glaring issues in how mount options were being
treated. The key changes are:
- Mount options on bind-mounts that clear a mount flag are now always
applied. Previously, if a user requested a bind-mount with only clearing
options (such as rw,exec,dev) the options would be ignored and the
original bind-mount options would be set. Unfortunately this also means
that container configurations which specified only clearing mount options
will now actually get what they asked for, which could break existing
containers (though it seems unlikely that a user who requested a specific
mount option would consider it "broken" to get the mount options they
asked foruser who requested a specific mount option would consider it
"broken" to get the mount options they asked for). This also allows us to
silently add locked mount flags the user did not explicitly request to be
cleared in rootless mode, allowing for easier use of bind-mounts for
rootless containers.
- Container configurations using bind-mounts with superblock mount flags
(i.e. filesystem-specific mount flags, referred to as "data" in
mount(2), as opposed to VFS generic mount flags like MS_NODEV) will
now return an error. This is because superblock mount flags will also
affect the host mount (as the superblock is shared when bind-mounting),
which is obviously not acceptable. Previously, these flags were silently
ignored so this change simply tells users that runc cannot fulfil their
request rather than just ignoring it.
Deprecated
- runc option --criu is now ignored (with a warning), and the option will
be removed entirely in a future release. Users who need a non-standard
criu binary should rely on the standard way of looking up binaries in
$PATH.
- runc kill option -a is now deprecated. Previously, it had to be specified
to kill a container (with SIGKILL) which does not have its own private PID
namespace (so that runc would send SIGKILL to all processes). Now, this is
done automatically.
- github.com/opencontainers/runc/libcontainer/user is now deprecated, please
use github.com/moby/sys/user instead. It will be removed in a future
release.
