Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4452-1 advisory.

Trent Shea working with Trend Micros Zero Day Initiative, discovered that the libvirt package set incorrect permissions on the UNIX domain socket. A local attacker could use this issue to access libvirt and escalate privileges.
