USN-2214-1: libxml2 vulnerability

Releases

• Ubuntu 14.04 ESM
• Ubuntu 13.10
• Ubuntu 12.10
• Ubuntu 12.04
• Ubuntu 10.04

Packages

• libxml2 - GNOME XML library

Details

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.

Update instructions

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

Ubuntu 14.04

• 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

• libxml2 - 2.7.8.dfsg-5.1ubuntu4.7

Ubuntu 10.04

• libxml2 - 2.7.6.dfsg-1ubuntu1.11

After a standard system update you need to reboot your computer to make
all the necessary changes.
