Summary
Red Hat Security Advisory: docker-latest security, bug fix, and enhancement update
Notes
Topic
An update for docker-latest is now available for Red Hat Enterprise Linux 7 Extras.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Docker is an open-source engine that automates the deployment of any application as a lightweight, portable, and self-sufficient container that will run virtually anywhere.
The following packages have been upgraded to a newer upstream version: docker-latest (1.12.5). (BZ#1404309)
Security Fix(es):
* The runc component used by `docker exec` feature of docker allowed additional container processes via to be ptraced by the pid 1 of the container. This allows the main processes of the container, if running as root, to gain low-level access to these new processes during initialization. An attacker can, depending on the nature of the incoming process, leverage this to elevate access to the host. This ranges from accessing host content through the file descriptors of the incoming process to, potentially, a complete container escape by leveraging memory access or syscall interception. (CVE-2016-9962)
Red Hat would like to thank the Docker project for reporting this issue. Upstream acknowledges Aleksa Sarai (SUSE) and Tonis Tiigi (Docker) as the original reporters.
