Ubuntu 13.10 : lxc vulnerability (USN-2104-1)

High Nessus Plugin ID 72479


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


Florian Sagar discovered that the LXC sshd template set incorrect mount permissions. An attacker could possibly use this flaw to cause privilege escalation on the host.

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-templates package.
