Ubuntu 14.04 LTS / 16.04 LTS : LXC vulnerability (USN-3224-1)

low Nessus Plugin ID 97659

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3224-1 advisory.

 Jann Horn discovered that LXC incorrectly verified permissions when creating virtual network interfaces. A local attacker could possibly use this issue to create virtual network interfaces in network namespaces that they do not own.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
