Containerd incorrectly handled file permission changes.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

if a user or automated system were tricked into launching a specially crafted container image, a remote attacker could change permissions on files on the host filesystem and possibly escalate privileges.

  • CVSS V2 rated as High - 6.8 severity.
