Description Trevor Jay 2014-12-10 12:51:17 EST

Docker Inc. has discovered an issue whereby a malicious image could execute arbitrary code when being unpacked automatically after a "docker pull". From the Docker Inc report:

"It has been discovered that the introduction of chroot for archive extraction in Docker 1.3.2 had introduced a privilege escalation vulnerability. Malicious images or builds from malicious Dockerfiles could escalate privileges and execute arbitrary code as a root user on the Docker host by providing a malicious ‘xz’ binary.

We are releasing Docker 1.3.3 to address this vulnerability. Only Docker 1.3.2 is vulnerable. Users are highly encouraged to upgrade."

Comment 1 Trevor Jay 2014-12-10 12:51:57 EST

Statement:

This issue affects the versions of Docker as shipped with Red Hat Enterprise Linux 7. However, this flaw is not known to be exploitable under any supported scenario. A future update may address this issue.

Red Hat does not support or recommend running untrusted images.
