Detail

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.10 - Ubuntu 12.04 LTS - Ubuntu 11.10 - Ubuntu 10.04 LTS - Ubuntu 8.04 LTS

Summary:

libxml2 could be made to hang if it received specially crafted input.

Software Description: - libxml2: GNOME XML library

Details:

It was discovered that libxml2 incorrectly handled XML entity expansion. An attacker could use this flaw to cause libxml2 to consume large amounts of resources, resulting in a denial of service.

Update instructions:

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

Ubuntu 12.10:
libxml2 2.8.0+dfsg1-5ubuntu2.2

Ubuntu 12.04 LTS:
libxml2 2.7.8.dfsg-5.1ubuntu4.4

Ubuntu 11.10:
libxml2 2.7.8.dfsg-4ubuntu0.6

Ubuntu 10.04 LTS:
libxml2 2.7.6.dfsg-1ubuntu1.8

Ubuntu 8.04 LTS:
libxml2 2.6.31.dfsg-2ubuntu1.12

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