Ubuntu 14.04 LTS / 16.04 LTS / 16.10 : lxc vulnerability (USN-3136-1)

High Nessus Plugin ID 95295


The remote Ubuntu host is missing one or more security-related patches.


Roman Fiedler discovered a directory traversal flaw in lxc-attach. An attacker with access to an LXC container could exploit this flaw to access files outside of 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 liblxc1, lxc and / or lxc1 packages.
