Medium Nessus Plugin ID 81019


The remote Ubuntu host is missing one or more security-related patches.


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.

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.


Update the affected libunbound2 and / or unbound packages.
