Vulnerability from cvelistv5 – Published: 2017-01-31 22:00 – Updated: 2024-08-06 03:07
VLAI
Summary
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.
