USN-3201-1: Bind vulnerabilities
Ubuntu Security Notice USN-3201-1
16th February, 2017
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.10
- Ubuntu 16.04 LTS
- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS
Bind could be made to crash if it received specially crafted network traffic.
- bind9 - Internet Domain Name Server
It was discovered that Bind incorrectly handled rewriting certain query
responses when using both DNS64 and RPZ. A remote attacker could possibly
use this issue to cause Bind to crash, resulting in a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 16.10:
- bind9 1:9.10.3.dfsg.P4-10.1ubuntu1.3
- Ubuntu 16.04 LTS:
- bind9 1:9.10.3.dfsg.P4-8ubuntu1.5
- Ubuntu 14.04 LTS:
- bind9 1:9.9.5.dfsg-3ubuntu0.13
- Ubuntu 12.04 LTS:
- bind9 1:9.8.1.dfsg.P1-4ubuntu0.21
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
In general, a standard system update will make all the necessary changes.
