runc: AppArmor/SELinux bypass with malicious image that specifies a volume at /proc

runc through 1.0.0-rc8, as used in Docker through 19.03.2-ce and other products, allows AppArmor restriction bypass because libcontainer/rootfslinux.go incorrectly checks mount targets, and thus a malicious Docker image can mount over a /proc directory...

The vulnerability of the fusermount module in file system drivers for UNIX-like operating systems allows a attacker to cause a service failure or other unpredictable behavior.

The vulnerability of the fusermount driver for file systems in UNIX-like operating systems relates to circumventing a limitation under SELinux’s mandatory access control policy. This allows users without root privileges to mount the FUSE file system with the “allowother” mount option, regardless ...
