Summary
containerd vulnerability
Details

It was discovered that containerd insufficiently restricted permissions on container root and plugin directories. If a user or automated system were tricked into launching a specially crafted container image, a remote attacker could traverse directory contents and modify files and execute programs on the host filesystem, possibly leading to privilege escalation.
