Description: libxml2 is a library for parsing and manipulating XML files. It includes support for reading, modifying, and writing XML and HTML files. An integer overflow flaw causing a heap-based buffer overflow was found in the libxml2 XML parser. If an application linked against libxml2 processed untrusted, malformed XML content, it could cause the application to crash or, possibly, execute arbitrary code. (CVE-2008-4226) A denial of service flaw was discovered in the libxml2 XML parser. If an application linked against libxml2 processed untrusted, malformed XML content, it could cause the application to enter an infinite loop. (CVE-2008-4225) Red Hat would like to thank Drew Yao of the Apple Product Security team for reporting these issues. Users of libxml2 are advised to upgrade to these updated packages, which contain backported patches to correct these issues. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/FAQ_58_10188 5.
