Zero Day Initiative Advisory 10-237 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Novell GroupWise. Authentication is not required to exploit this vulnerability. The specific flaw exists within the gwia.exe module responsible for parsing e-mail messages received by the server. When the code encounters a Content-Type header it proceeds to parse out the entities within its contents, separated by a semicolon. The process does not properly check the size of these values before copying them individually to a fixed-length stack buffer. This can be abused by an attacker to overflow the buffer and subsequently execute arbitrary code under the context of the SYSTEM user.
