Overview
Affected versions of this package are vulnerable to Improper Privilege Management due to the process handling custom storage volumes with the security.shifted property set to true. An attacker can gain elevated privileges on the host system by creating a custom storage volume, writing a setuid binary from within a container, and executing it as an unprivileged user on the host.
Note:
This is only exploitable if an unprivileged user has root access inside a container with an attached custom storage volume configured with the security.shifted property and also has unprivileged access to the host.
Workaround
This vulnerability can be mitigated by manually restricting permissions to prevent unprivileged users from attaching custom storage volumes with the security.shifted property.
