COMMAND
NTMail
SYSTEMS AFFECTED
NTMail V5 and V6 Alpha and Intel Processor
PROBLEM
Following is based on Advisorz VIGILANTE-2000008. The web
configuration running on TCP port 8000 does not flush incomplete
HTTP requests, and thus it is possible to use up all the server
ressources within a very short time. During testing the CPU usage
stayed around 90-99% and within 2 minutes the www.exe service had
consumed more than 250MB of memory. An attack might result in the
service crashing, when the system hits the maximum pagefile size.
