Novell GroupWise Messenger Accept-Language Buffer Overflow Vulnerability

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of the Novell GroupWise Messenger. Authentication is not required to exploit this vulnerability. The specific flaw exists within the Novell Messaging Agent, a web server that listens by default on TCP port 8300. Insufficient length checks during the parsing of long parameters within the Accept-Language header results in an exploitable stack overflow under the context of the SYSTEM user.
