CVE-2016-9962
RunC - Ptrace Vulnerability
Description
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.

Action Type Old Value New Value Changed Description Race condition in Docker Engine before 1.12.6 might allow local root users in a container to gain privileges by using ptrace to access file-descriptors of a process launched or moved into the container from another namespace, aka an "on-entry vulnerability." 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. -
