LinuxSecurity.com: Drew Yaro of the Apple Product Security Team found two flaws in libxml2. The first is a denial of service flaw in libxml2's XML parser. If an application linked against libxml2 were to process certain malformed XML content, it cause the application to enter an infinite loop (CVE-2008-4225).
