Dear Andrey, can you give your comments on why vulnerability that looks so dangerous according to description (remote kernel-level buffer overflow in ICMP processing, according to MS) rated "high", not "critical"? Are there are mitigating factors for Windows 2003 with RRAS enabled or any RRAS installation is vulnerable? P.S. last instruction I've got was to publish information only after vendor's fix. I did :) --Wednesday, June 28, 2006, 11:01:51 PM, you wrote to 3APA3A@xxxxxxxxxxxxxxxx: Ì> Hi All, Ì> At the request Microsoft I have not published the additional Ì> information.
