Debian Security Advisory DSA-1666-1 security@debian.org
http://www.debian.org/security/ Moritz Muehlenhoff
November 17, 2008 http://www.debian.org/security/faq
- ------------------------------------------------------------------------

Package : libxml2
Vulnerability : several
Problem type : local(remote)
Debian-specific: no
CVE Id(s) : CVE-2008-4225 CVE-2008-4226

Several vulnerabilities have been discovered in the GNOME XML library.
The Common Vulnerabilities and Exposures project identifies the
following problems:

CVE-2008-4225

Drew Yao discovered that missing input sanitising in the
xmlBufferResize() function may lead to an infinite loop,
resulting in denial of service.

CVE-2008-4226

Drew Yao discovered that an integer overflow in the
xmlSAX2Characters() function may lead to denial of service or
the execution of arbitrary code.

For the stable distribution (etch), these problems have been fixed in
version 2.6.27.dfsg-6.

For the upcoming stable distribution (lenny) and the unstable
distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your libxml2 packages.

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

apt-get upgrade
will install corrected packages

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


Debian GNU/Linux 4.0 alias etch
