Ubuntu Security Notice USN-1843-1
29th May, 2013
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
GnuTLS could be made to crash if it received specially crafted network traffic.
- gnutls26 - GNU TLS library
It was discovered that GnuTLS incorrectly handled certain padding bytes. A
remote attacker could use this flaw to cause an application using GnuTLS to
crash, leading to a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 13.04:
- libgnutls26 2.12.23-1ubuntu1.1
- Ubuntu 12.10:
- libgnutls26 2.12.14-5ubuntu4.3
- Ubuntu 12.04 LTS:
- libgnutls26 2.12.14-5ubuntu3.4
- Ubuntu 10.04 LTS:
- libgnutls26 2.8.5-2ubuntu0.4
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.
