Description:
A vulnerability has been reported in Novell GroupWise Messenger, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within the Novell Messaging Agent service (port 8300/tcp) when processing the "Accept-Language:" header. This can be exploited to cause a stack-based buffer overflow via an overly long string (more than 16 characters) not containing "," or ";" characters.
Successful exploitation allows execution of arbitrary code.
The vulnerability has been reported in Novell GroupWise Messenger 2.0.
