Amazon Linux AMI Security Advisory: ALAS-2017-783
Advisory Release Date: 2017-01-10 18:00 Pacific
Severity: Important
References: CVE-2016-9962 

Issue Overview:

It was discovered that 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, which can lead to container escapes or modification of runC state before the process is fully placed inside the container.
