Ubuntu 14.04 LTS / 15.04 : lxc vulnerability (USN-2753-1)

High Nessus Plugin ID 86208


The remote Ubuntu host is missing a security-related patch.


Roman Fiedler discovered a directory traversal flaw in lxc-start. A local attacker with access to an LXC container could exploit this flaw to run programs inside the container that are not confined by AppArmor or expose unintended files in the host to the container.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected lxc package.
