CVE-2016-9962 Detail

Modified After Enrichment

This CVE record has been updated after NVD enrichment efforts were completed. Enrichment data supplied by the NVD may require amendment due to these changes.

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.

CVE Modified by MITRE 4/11/2017 9:59:00 PM

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.
