Several important security issues were identified in the runC Open Container Project. It was discovered that runC incorrectly performed access control when mounting /proc to non-directories (CVE-2023-27561), and incorrectly handled /proc and /sys mounts inside a container (CVE-2023-28642).

These bugs could possibly allow an attacker to escalate privileges or bypass AppArmor, and potentially SELinux.

A runC security update that fixes these flaws has been released. We strongly recommend that all impacted users apply the runC updates issued by their distro(s) as soon as possible to protect the confidentiality, integrity and availability of their systems.
