NVD Description

Note: Versions mentioned in the description apply only to the upstream skopeo-tests package and not the skopeo-tests package as distributed by Centos. See How to fix? for Centos:8 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.
