Subject: Re: MS03-039 has been released (DoS) sploit ?

this exploit was released at the same time as MS03-026, BUT that patch was not made for this exploit, it was against the bof.
 
Only the MS03-039 protect you against this sploit
 
http://www.k-otik.com/exploits/07.21.win2kdos.c.php
 
About MS03-039, the exploit (eeye) is public in nessus plugin :

Seems guys you are mistaking. Here is the NSfocus advisory. In fact they found (as the M$ advisory is not clear on the subject) the 2nd BoF(CAN-2003-0528)  and not the DoS. The one you are talking of is an old (few weeks) vulnerability related to MS03-026 found by Ben Jurry.

Sure looks that way, especially with the 7/21 datestamp for the directory and in the page name :-)
 
  It's *very* unlikely that we see a worm that acts on the DoS vuln, it's just too much work.  The BoF's are the ones that has my attention and need to patch urgently.
