Secunia reports :
Two vulnerabilities have been reported in Libxml2, which can be exploited by malicious people to cause a DoS (Denial of Service) or to potentially compromise an application using the library.
Successful exploitation may allow execution of arbitrary code, but requires e.g. that the user is tricked into processing an overly large XML file (2GB or more).
Other versions may also be affected.
