How to fix?

Upgrade Alpine:3.12 containerd to version 1.3.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream containerd package and not the containerd package as distributed by Alpine. See How to fix? for Alpine:3.12 relevant fixed versions and status.

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfs_linux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory.
