RE: [ActiveDir] New RPC DOS

[Roger Seielstad]

Title: Message

The solution is to do away with RPC entirely - but that's a major rewrite of things. On the other hand, I have plenty of Unix boxes running with RPC disabled and they run fine.

 

Let's remember RPC's major functionality can be replaced, but that's at the expense of more complex application design.

Todd,

Concentrate maybe one or two more people on looking at error checking on the input into the arrays/buffers in the RPC code?  ;op

 

I mean, really - a vuln lays around waiting for someone to find it for years, and in this short of a time 3 more vuls are found in roughly the same area, just different vectors?  I sure hope that there is a team pouring over the code that makes up RPC.

Our Microsoft TAM notified us of this new issue.  I waited to give them time to publish it to the various news sites. 

 

At 9AM PST, PSS will be announcing a new critical security bulletin (MS03-039).   This bulletin will address an RPC denial-of-service vulnerability in Windows products.    Please take the time today to go to the www.microsoft.com/security site to obtain the patch and directions for implementation.    Just trying to help you stay one step ahead!

 

I think it is very important to get this update on all your DC's even if they are behind a firewall ASAP.  We managed to mitigate blaster but these RPC DOS are starting to get really nasty.

 

Anyone have a clue as to how Microsoft plans to fix the RPC system to make it more secure?

 

Thanks,

 

Todd Myrick
