Descriptions

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.

runc versiones hasta 1.0.0-rc8, como es usado en Docker versiones hasta 19.03.2-ce y otros productos, permite omitir la restricción de AppArmor porque el archivo libcontainer/rootfs_linux.go comprueba incorrectamente los destinos de montaje y, por lo tanto, una imagen Docker maliciosa puede ser montada sobre un directorio /proc .
