Test ID:1.3.6.1.4.1.25623.1.0.61608
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-640-1 (libxml2)
Summary:Ubuntu USN-640-1 (libxml2)
Description:
The remote host is missing an update to libxml2
announced via advisory USN-640-1.

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 7.04
Ubuntu 7.10
Ubuntu 8.04 LTS

This advisory also applies to the corresponding versions of
Kubuntu, Edubuntu, and Xubuntu.

Details follow:

Andreas Solberg discovered that libxml2 did not handle recursive entities
safely. If an application linked against libxml2 were made to process
a specially crafted XML document, a remote attacker could exhaust the
system's CPU resources, leading to a denial of service.

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

Ubuntu 6.06 LTS:
libxml2 2.6.24.dfsg-1ubuntu1.2

Ubuntu 7.04:
libxml2 2.6.27.dfsg-1ubuntu3.2

Ubuntu 7.10:
libxml2 2.6.30.dfsg-2ubuntu1.2

Ubuntu 8.04 LTS:
libxml2 2.6.31.dfsg-2ubuntu1.1

In general, a standard system upgrade is sufficient to effect the
necessary changes.
