- ------------------------------------------------------------------------

Package : libxml2
Vulnerability : invalid memory access
Problem type : local (remote)
Debian-specific: no
CVE ID : CVE-2010-4008

Bui Quang Minh discovered that libxml2, a library for parsing and
handling XML data files, does not well process a malformed XPATH,
causing crash and allowing arbitrary code execution.

For the stable distribution (lenny), this problem has been fixed in
version 2.6.32.dfsg-5+lenny2.

For the testing (squeeze) and unstable (sid) distribution, this problem
has been fixed in version 2.7.8.dfsg-1.

We recommend that you upgrade your libxml2 package.

Upgrade instructions
- --------------------

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
will update the internal database
apt-get upgrade
will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
