Re: TSRT-06-02: Microsoft SRV.SYS Mailslot Ring0 Memory Corruption Vulnerability



After furiously patching since last week for catching up with MS06-040, we 
discovered that a old exploit for MS06-035 (again or still) works on a number 
fully patched systems including Windows 2003 Server, Windows XP and Windows 
2000.

The exploit that works is: http://milw0rm.org/exploits/2057

All our tested systems (8 total) except one went into reboot after being hit 
with the exploit above. All tested systems have been patched with the latest 
available patches from Microsoft as of today, August 14th, 2006 4:00 PM MESZ, 
using both the standard Windows Update function and applying patches by hand.
Explicit download of KB917159 patch, applying it and reboot, with no result. I 
carefully checked the version of the srv.sys binary according to 
http://www.microsoft.com/technet/security/bulletin/ms06-035.mspx and found it 
to be correct, meaning the patch should be applied correctly.

My only conclusion at this time is that the Microsoft delivered patch for 
MS06-035 does not work. Can anyone confirm this behaviour?

Thanks,
Frank
