Novell GroupWise Messenger Accept-Language Buffer Overflow
------------------------------------------------------------------------
SUMMARY
" <http://www.novell.com/products/groupwise/> Novell GroupWise is a
complete collaboration software solution that provides information workers
with e-mail, calendaring, instant messaging, task management, and contact
and document management functions."

using Novell GroupWise Messenger.
DETAILS
Vulnerable Systems:
* Novell GroupWise Messenger 2
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.

Public Beta 2. The fix will also be included in the shipping release of
Messenger 2.0 SP1. TID #NOVL105592 further details the specifics of the
