Rating: Less Critical Impact: System access Where: Local Network

====================================================================== 3) Description of Vulnerability

Secunia research has discovered a vulnerability in Novell NetMail, which can be exploited by malicious people to compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the NMAP (Network Messaging Application Protocol) Agent when handling an overly long user name in the "USER" command. This can be exploited to cause a stack-based buffer overflow and allows arbitrary code execution.

Successful exploitation requires valid logon to the NMAP Agent (e.g. if the default NMAP authentication credential has not been changed).
