CVE-2019-16884  (opens in a new tab)
CWE-863  (opens in a new tab)

How to fix?

Upgrade Debian:11 runc to version 1.0.0~rc9+dfsg1-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream runc package and not the runc package as distributed by Debian. See How to fix? for Debian:11 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.
