Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2023-03-26 01:19:16 UTC 
runc through 1.1.4 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. NOTE: this issue exists because of a CVE-2019-19921 regression.

Comment 2 Mathieu Tortuyaux 2023-03-29 10:10:28 UTC 
runc 1.1.5 is out and it fixes two more CVEs:

* 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.

* CVE-2023-28642: is a variant of the same bug and was fixed by the same
patch. This variant of the above vulnerability was reported by Lei Wang.
