Ubuntu Security Notice USN-1518-1
26th July, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS
Bind could be made to crash if it received specially crafted network traffic.
- bind9 - Internet Domain Name Server
Einar Lonn discovered that Bind incorrectly initialized the failing-query
cache. A remote attacker could use this flaw 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 12.04 LTS:
- libdns81 1:9.8.1.dfsg.P1-4ubuntu0.2
- Ubuntu 11.10:
- libdns69 1:9.7.3.dfsg-1ubuntu4.3
- Ubuntu 11.04:
- libdns69 1:9.7.3.dfsg-1ubuntu2.5
- Ubuntu 10.04 LTS:
- libdns64 1:9.7.0.dfsg.P1-1ubuntu0.6
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.
