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).
