Test ID:1.3.6.1.4.1.25623.1.0.61912
Category:Ubuntu Local Security Checks
Title:Ubuntu USN-673-1 (libxml2)
Summary:Ubuntu USN-673-1 (libxml2)
Description:
The remote host is missing an update to libxml2
announced via advisory USN-673-1.

A security issue affects the following Ubuntu releases:

Ubuntu 6.06 LTS
Ubuntu 7.10
Ubuntu 8.04 LTS
Ubuntu 8.10

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

Details follow:

Drew Yao discovered that libxml2 did not correctly handle certain corrupt
XML documents. If a user or automated system were tricked into processing
a malicious XML document, a remote attacker could cause applications
linked against libxml2 to enter an infinite loop, leading to a denial
of service. (CVE-2008-4225)

Drew Yao discovered that libxml2 did not correctly handle large memory
allocations. If a user or automated system were tricked into processing a
very large XML document, a remote attacker could cause applications linked
against libxml2 to crash, leading to a denial of service. (CVE-2008-4226)

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

Ubuntu 6.06 LTS:
libxml2 2.6.24.dfsg-1ubuntu1.4

Ubuntu 7.10:
libxml2 2.6.30.dfsg-2ubuntu1.4

Ubuntu 8.04 LTS:
libxml2 2.6.31.dfsg-2ubuntu1.3

Ubuntu 8.10:
libxml2 2.6.32.dfsg-4ubuntu1.1

After a standard system upgrade you need to restart your sessions to effect
the necessary changes.
