Ubuntu Security Notice USN-2214-1
15th May, 2014
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS
libxml2 could be made to consume resources if it processed a specially crafted file.
- libxml2 - GNOME XML library
Daniel Berrange discovered that libxml2 would incorrectly perform entity
substitution even when requested not to. If a user or automated system were
tricked into opening a specially crafted document, an attacker could
possibly cause resource consumption, resulting in a denial of service.
The problem can be corrected by updating your system to the following package version:
- Ubuntu 14.04 LTS:
- libxml2 2.9.1+dfsg1-3ubuntu4.1
- Ubuntu 13.10:
- libxml2 2.9.1+dfsg1-3ubuntu2.1
- Ubuntu 12.10:
- libxml2 2.8.0+dfsg1-5ubuntu2.5
- Ubuntu 12.04 LTS:
- libxml2 2.7.8.dfsg-5.1ubuntu4.7
- Ubuntu 10.04 LTS:
- libxml2 2.7.6.dfsg-1ubuntu1.11
To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades.
After a standard system update you need to reboot your computer to make
all the necessary changes.
