Summary

A flaw was found in Podman, where containers were started incorrectly with non-empty default permissions. A vulnerability was found in Moby (Docker Engine), where containers were started incorrectly with non-empty inheritable Linux process capabilities. This flaw allows an attacker with access to programs with inheritable file capabilities to elevate those capabilities to the permitted set when execve(2) runs.
