Ubuntu 12.04 LTS : linux vulnerability (USN-2640-1)

High Nessus Plugin ID 84208


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


Philip Pettersson discovered a privilege escalation when using overlayfs mounts inside of user namespaces. A local user could exploit this flaw to gain administrative privileges on the system.

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 packages.
