Container Escape Vulnerability in RunC via 'runc exec'

CVE-2016-9962 · MEDIUM Severity

AV:L/AC:M/AU:N/C:P/I:P/A:P

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.
