• CVE-2023-25809 is a vulnerability involving rootless containers where(under specific configurations), the container would have write accessto the /sys/fs/cgroup/user.slice/... cgroup hierarchy. No otherhierarchies on the host were affected. This vulnerability wasdiscovered by Akihiro Suda.GHSA-m8cg-xc2p-r3fc

• CVE-2023-27561 was a regression which effectively re-introducedCVE-2019-19921. This bug was present from v1.0.0-rc95 to v1.1.4. Thisregression was discovered by@​Beuc.GHSA-vpvm-3wq2-2wvm

In addition, the following other fixes are included in this release:

• Fix the inability to use/dev/null when inside a container. (#3620)
• Fix changing the ownership of host's/dev/null caused by fd redirection(a regression in 1.1.1). (#3674,#3731)
• Fix rare runc exec/enter unshare error on older kernels, includingCentOS < 7.7. (#3776)
• nsexec: Check for errors inwrite_log(). (#3721)

[1.1.5] - 2023-03-29

囚われた屈辱は反撃の嚆矢だ

Fixed

• Prohibit container's/proc and/sys to be symlinks (CVE-2019-19921,CVE-2023-27561,CVE-2023-28642,#3785)
• rootless: rework /sys/fs/cgroup mounts to avoid exposing the host's cgrouphierarchy into the container. (CVE-2023-25809)
• Fix the inability to use/dev/null when inside a container. (#3620)
• Fix changing the ownership of host's/dev/null caused by fd redirection(a regression in 1.1.1). (#3674,#3731)
• Fix rare runc exec/enter unshare error on older kernels, inlcudingCentOS < 7.7. (#3776)
• nsexec: Check for errors inwrite_log(). (#3721)
• Various CI fixes and updates. (#3618,#3630,#3640,#3729)

[1.1.4] - 2022-08-24

If you look for perfection, you'll never be content.

Fixed

• Fix mounting via wrong proc fd.When the user and mount namespaces are used, and the bind mount is followed bythe cgroup mount in the spec, the cgroup was mounted using the bind mount'smount fd. (#3511)
• Switchkill() inlibcontainer/nsenter tosane_kill(). (#3536)
• Fix "permission denied" error fromrunc run onnoexec fs. (#3541)
• Fix failed exec aftersystemctl daemon-reload.Due to a regression in v1.1.3, theDeviceAllow=char-pts rwm rule was nolonger added and was causing an erroropen /dev/pts/0: operation not permitted: unknownwhen systemd was reloaded. (#3554)
• Various CI fixes. (#3538,#3558,#3562)

[1.1.3] - 2022-06-09

In the beginning there was nothing, which exploded.

Fixed

• Our seccomp-ENOSYS stub now correctly handles multiplexed syscalls ons390 and s390x. This solves the issue where syscalls the host kernel did notsupport would return-EPERM despite the existence of the-ENOSYS stubcode (this was due to how s390x does syscall multiplexing). (#3478)
• Retry on dbus disconnect logic in libcontainer/cgroups/systemd now works asintended; this fix does not affect runc binary itself but is important forlibcontainer users such as Kubernetes. (#3476)
• Inability to compile with recent clang due to an issue with duplicate
