Description

A vulnerability was discovered and corrected in libxml2 :

libxml2 before 2.7.8 reads from invalid memory locations during processing of malformed XPath expressions, which allows context-dependent attackers to cause a denial of service (application crash) via a crafted XML document (CVE-2010-4008).

Packages for 2009.0 are provided as of the Extended Maintenance Program. Please visit this link to learn more: http://store.mandriva.com/product_info.php?cPath=149&products_id=4 90

The updated packages have been patched to correct these issues.
