Ubuntu 18.04 LTS : lxc vulnerability (USN-3730-1)

Low Nessus Plugin ID 111577

Synopsis

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

Description

Matthias Gerstner discovered that LXC incorrectly handled the lxc-user-nic utility. A local attacker could possibly use this issue to open arbitrary files.

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.

Solution

Update the affected lxc package.
