The runC tool is a lightweight, portable implementation of the Open Container Format (OCF) that provides container runtime.

Security Fix(es):

  • golang: crypto/tls: large handshake records may cause panics (CVE-2022-41724)
  • runc: Rootless runc makes /sys/fs/cgroup writable (CVE-2023-25809)
  • runc: volume mount race condition (regression of CVE-2019-19921) (CVE-2023-27561)
  • runc: AppArmor can be bypassed when /proc inside the container is symlinked with a specific mount configuration (CVE-2023-28642)
  • runc: integer overflow in netlink bytemsg length field allows attacker to override netlink-based container configuration (CVE-2021-43784)
