UnknownEPSS 0.38%

Last modified

CVE-2016-9962 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.38% chance of exploitation in the next 30 days.
