Release notes

Sourced from github.com/opencontainers/runc's releases.

runc 1.1.12 -- "Now you're thinking with Portals™!"

This is the twelfth patch release in the 1.1.z release branch of runc. It fixes a high-severity container breakout vulnerability involving leaked file descriptors, and users are strongly encouraged to update as soon as possible.

• Fix CVE-2024-21626, a container breakout attack that took advantage of a file descriptor that was leaked internally within runc (but never leaked to the container process).

  In addition to fixing the leak, several strict hardening measures were added to ensure that future internal leaks could not be used to break out in this manner again.

  Based on our research, while no other container runtime had a similar leak, none had any of the hardening steps we've introduced (and some runtimes would not check for any file descriptors that a calling process may have leaked to them, allowing for container breakouts due to basic user error).

Static Linking Notices

The runc binary distributed with this release are statically linked with the following GNU LGPL-2.1 licensed libraries, with runc acting as a "work that uses the Library":

• libseccomp

The versions of these libraries were not modified from their upstream versions, but in order to comply with the LGPL-2.1 (§6(a)), we have attached the complete source code for those libraries which (when combined with the attached runc source code) may be used to exercise your rights under the LGPL-2.1.

However we strongly suggest that you make use of your distribution's packages or download them from the authoritative upstream sources, especially since these libraries are related to the security of your containers.

Thanks to all of the contributors who made this release possible:

Happy New Year!

Fixed

• Fix several issues with userns path handling. (#4122, #4124, #4134, #4144)

Changed

• 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. (#4000, #4010, #4131)
• build(deps): bump github.com/cyphar/filepath-securejoin. (#4140)

Just a heads up for folks in the community. This patches CVE-2024-21626, but we're assessing how this actually impacts Nomad users. Only the exec/java drivers in Nomad use libcontainer directly and neither supports OCI images. In any case, we'll get this merged ASAP and then shipped soon.
