CVE-2016-9962
6.4 · MEDIUMOverview
CVE-2016-9962 is a medium-severity vulnerability affecting docker docker. It was published on January 31, 2017 and has a CVSS 3.0 base score of 6.4 (MEDIUM).
This vulnerability has a CVSS 3.0 base score of 6.4, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from docker. Update docker to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
