USN-4197-1: Bind vulnerability

21 November 2019

Bind could be made to consume resources if it received specially crafted network traffic.



  • bind9 - Internet Domain Name Server


It was discovered that Bind incorrectly handled certain TCP-pipelined
queries. A remote attacker could possibly use this issue to cause Bind to
consume resources, resulting in a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 19.10
Ubuntu 19.04
Ubuntu 18.04

In general, a standard system update will make all the necessary changes.
