Novell GroupWise Internet Agent HTTP Interface Buffer Overflow

Novell GroupWise Internet Agent HTTP Interface Buffer Overflow
Posted Sep 27, 2011
Authored by Carsten Eiram | Site secunia.com

Secunia Research has discovered a vulnerability in Novell GroupWise, which can be exploited by malicious users to cause a DoS (Denial of Service) and potentially compromise a vulnerable system. The vulnerability is caused by a boundary error in GroupWise Internet Agent (gwia.exe) within the HTTP interface (port 9850/tcp) when handling requests for certain .css resources. This can be exploited to cause a limited stack-based buffer overflow via a specially crafted, overly long request.
