Novell NetMail NMAP Agent "USER" Buffer Overflow
------------------------------------------------------------------------
SUMMARY
" <http://www.novell.com/products/netmail/> Novell NetMail is an e-mail
and calendaring system that is based on Internet-standard messaging and
security protocols."
Lack of proper length checking allow attackers to execute arbitrary code
by overflowing an internal buffer used by the Novell NetMail.
DETAILS
Vulnerable Systems:
* Novell NetMail version 3.52C
Immune Systems:
* Novell NetMail version 3.52D
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).
