Description Sam James archtester Gentoo Infrastructure gentoo-dev Security 2020-03-01 17:18:13 UTC 
Description:
"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."

@ maintainer(s): Please cleanup and drop =app-emulation/runc-1.0.0_rc8!
