Situation
The GroupWise Internet Agent (GWIA) has multiple vulnerabilities in the way that it parses variables within a received VCALENDAR message, which could potentially allow an unauthenticated remote attacker to execute arbitrary code on vulnerable installations of GWIA.
These vulnerabilities were discovered and reported by Anonymous working with TippingPoint's Zero Day Initiative (http://www.zerodayinitiative.com), ZDI-CAN-954, ZDI-CAN-955, ZDI-CAN-960, ZDI-CAN-961
Novell bugs 642339, 642345, 642349, 642340
NOTE: The Tippingpoint/ZDI advisory specifically references "the gwwww1.dll module" because the person who reported the issue to ZDI tested GWIA on Windows Server. However, this vulnerability affects GWIA running on all supported server OS platforms (Windows, SuSE Linux, & NetWare), and is NOT specific to Windows.
