CWE-41  (opens in a new tab)

How to fix?

Upgrade RHEL:7 runc to version 0:1.0.0-67.rc10.el7_8 or higher.
This issue was patched in RHBA-2020:1232.

NVD Description

Note: Versions mentioned in the description apply only to the upstream runc package and not the runc package as distributed by RHEL. See How to fix? for RHEL:7 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.
