Issue Overview:
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. (CVE-2019-16884)
Affected Packages:
runc
Issue Correction:
Run yum update runc to update your system.
