Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4365-1 advisory.

 Lior Shafir, Yehuda Afek, and Anat Bremler-Barr discovered that Bind incorrectly limited certain fetches.
 A remote attacker could possibly use this issue to cause Bind to consume resources, leading to a denial of service, or possibly use Bind to perform a reflection attack. (CVE-2020-8616)

 Tobias Klein discovered that Bind incorrectly handled checking TSIG validity. A remote attacker could use this issue to cause Bind to crash, resulting in a denial of service, or possibly perform other attacks.
 (CVE-2020-8617)

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

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