runc: opencontainers/selinux: container escape and denial of service due to arbitrary write gadgets and procfs write redirects

A flaw was found in runc. This attack is a more sophisticated variant of CVE-2019-16884, which was a flaw that allowed an attacker to trick runc into writing the LSM process labels for a container process into a dummy tmpfs file and thus not apply the correct LSM labels to the container process...

runc: container escape via 'masked path' abuse due to mount race conditions

A flaw was found in runc. This flaw exploits an issue with how masked paths are implementedin runc. When masking files, runc will bind-mount the container's /dev/null inode on top of the file. However, if an attacker can replace /dev/null with a symlink to some other procfs file, runc will instea...

Astra Linux – Vulnerability in runc-app

Runc is a CLI tool for spawning and running containers according to the OCI specification. In versions 1.2.7, 1.3.2, and 1.4.0-rc.2, an attacker can trick runc into redirecting write operations to /proc to other procfs files by using a racing container with shared mounts. We have also verified th...
