high Nessus Plugin ID 81019

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 14.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-2484-1 advisory.

 Florian Maury discovered that Unbound incorrectly handled delegation. A remote attacker could possibly use this issue to cause Unbound to consume resources, resulting in a denial of service.

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.
