USN-3535-1: Bind vulnerability

17 January 2018

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



  • bind9 - Internet Domain Name Server


Jayachandran Palanisamy discovered that the Bind resolver incorrectly
handled fetch cleanup sequencing. A remote attacker could possibly use this
issue to cause Bind to crash, resulting in a denial of service.

Update instructions

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

Ubuntu 17.10
Ubuntu 16.04
Ubuntu 14.04

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