While we're on the subject of MS holes... I'm not going to be covering these IE holes regularly as they are already heavily published elsewhere and MS are doing a pretty good job now a days at getting them out to users. But a couple of new problems are now covered by their latest IE Cumilative Patch. If you are using any IE5 or up on your machine or as part of the standard windows build in your company, you probably should install the patch. I'm not blaming MS for these holes, as I've said they've started to do a pretty good job. They did have some stupid ones in the past, but we can work with them now. In a complex piece of software like IE6, which consists of many different subcomponents its hard to find all of the problems up front. That said, these problems together with last years email panics, should help to underline why we need to protect our systems more than ever. The default approach I see many places is that companies panic and shut down net traffic all together. Thats not good for the business, the employees or the customers of the company. We are all part of the net now, and we should embrace that fact as an opportunity rather than a threat. What that does call for though is well thought out business applications and procedures.   6:32:54 PM     Local Security Vulnerability in Windows NT and Windows 2000 DebPloit uses a hole in the NT/2000 debugging subsystem and allows ANY user with ANY privileges (even Guest and Restricted user) to execute processes in the security context of an administrator or a local system (SYSTEM) account. In other words, any person who have an access to the local computer can became an administrator and do everything he/she wants. [Bugtraq] This could obviously  be an issue anywhere where NT Servers are used. I've verified it and it appears to work. The Authors of the exploit have an intermediate fix as well untill MS comes out with a bugfix. The source is available for the fix, so you might want to check it and compile it yourself. The risk of installing a third party fix like this might be even greater than the hole itself. You call the punches.   6:16:36 PM
