Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3909-1 advisory.

 It was discovered that libvirt incorrectly handled waiting for certain agent events. An attacker inside a guest could possibly use this issue to cause libvirtd to stop responding, resulting in a denial of service.
