NVD Description
Note: Versions mentioned in the description apply only to the upstream docker.io package and not the docker.io package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
RunC allowed additional container processes via 'runc exec' to be ptraced by the pid 1 of the container. This allows the main processes of the container, if running as root, to gain access to file-descriptors of these new processes during the initialization and can lead to container escapes or modification of runC state before the process is fully placed inside the container.
