-= OmniHTTPd Pro Denial of Service Vulnerability =-

Release date: Tuesday, May 15, 2001


Introduction:

OmniHTTPd Pro is a powerful all-purpose industry compliant web 
server built specifically for the Windows 9x and NT platforms. 

OmniHTTPd Pro can be obtained at vendor Omnicron Technologies' 
website: http://www.omnicron.ca


Problem:

The OmniHTTPd Pro web server is susceptible to a DoS through a 
lengthy POST request. If such a request is made to the server 
which exceeds 4111 bytes in size the server process will die. 
Neither the request or the crash are recorded in the server 
logfiles.


(..)


Solution:

The vendor was initially notified on the 23rd of April, 2001. After 
several attempts on our part to follow up on this, sales () omnicron ca 
on May 2nd told us the matter was under investigation. Momentarily 
no fix for the problem appears forthcoming.

This was tested against OmniHTTPd Pro v2.08 on WINNT4.
