Details

USN-4365-1 fixed several vulnerabilities in Bind. This update provides
the corresponding update for Ubuntu 12.04 ESM and 14.04 ESM.

Original advisory details:

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)
