The remote Debian host is missing a security-related update.


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.


Upgrade the libxml2 packages.

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 have been fixed in version 2.6.32.dfsg-5.
