Debian Security Advisory DSA-1631-1 security@debian.org
http://www.debian.org/security/ Steve Kemp
August 22, 2008 http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package : libxml2
Vulnerability : denial of service
Problem type : local
Debian-specific: no
CVE Id(s) : CVE-2008-3281

Andreas Solberg discovered that libxml2, the GNOME XML library,
could be forced to recursively evaluate entities, until available
CPU & memory resources were exhausted.

For the stable distribution (etch), this problem has been fixed in version
2.6.27.dfsg-3.

For the unstable distribution (sid), this problem will be fixed soon.

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.
