Ubuntu Security Notice USN-2214-1

libxml2 vulnerability
==========================================================================

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

Summary:

libxml2 could be made to consume resources if it processed a specially
crafted file.

Software Description:
– 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 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

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