Amazon Linux AMI : docker (ALAS-2014-461)

high Nessus Plugin ID 79875

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

Path traversal attacks are possible in the processing of absolute symlinks. In checking symlinks for traversals, only relative links were considered. This allowed path traversals to exist where they should have otherwise been prevented. This was exploitable via both archive extraction and through volume mounts. This vulnerability allowed malicious images or builds from malicious Dockerfiles to write files to the host system and escape containerization, leading to privilege escalation. (CVE-2014-9356)

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. (CVE-2014-9357)

It has been discovered that Docker does not sufficiently validate Image IDs as provided either via 'docker load' or through registry communications. This allows for path traversal attacks, causing graph corruption and manipulation by malicious images, as well as repository spoofing attacks. (CVE-2014-9358)

Solution

Run 'yum update docker' to update your system.
