NVD Description

Note: Versions mentioned in the description apply only to the upstream runc package and not the runc package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

runc through 1.0.0-rc9 has Incorrect Access Control leading to Escalation of Privileges, related to libcontainer/rootfs_linux.go. To exploit this, an attacker must be able to spawn two containers with custom volume-mount configurations, and be able to run custom images. (This vulnerability does not affect Docker due to an implementation detail that happens to block the attack.)
