New security advisory

Thursday, August 11, 2005

Hey folks – Mike Reavey here, live from the situation room. (BTW- “live from the situation room” is a new favorite term ever since our big television debut this week!) I wanted to let you know that we published an advisory on a security issue in COM object, MSDDS.DLL, that when loaded in Internet Explorer could potentially run malicious code a system.

MS05-038 Download Center Updates re-issued.

Wednesday, August 10, 2005

What a crazy 24 hours. We have now re-released MS05-038, the IE bulletin, as version 2.0. We have pushed out the updates to the Download Center with the digital signature issue resolved. If you got your updates from Windows Update, Microsoft Update, WSUS, or SUS yesterday you have nothing to worry about.

Today's Security Updates and bit of a glitch.

Tuesday, August 09, 2005

Much delayed post, but I’m sure some of you probably know or can take a good guess at what is causing my delay today. Not long after we released this morning, we found out that many of the digital signatures on some of the IE updates for MS05-038 were corrupted and were preventing install.

A virus for Windows Vista? Wrong.

Friday, August 05, 2005

Hi everyone, Stephen Toulouse here. There’s been some commentary the past couple of days regarding a potential Windows Vista virus and we wanted to weigh in with some details. First of all, in examining the details of the reports, there is no Windows Vista virus described in them. Instead, the reports are regarding potential proof of concept viruses in the form of malicious scripts that are developed to affect a new interactive shell codenamed “Monad”, which is currently in early phase of beta testing.

Slashdot article incorrect.

Friday, August 05, 2005

An article on Slashdot is saying that Monad was pulled from Windows Vista due to the virus story. This is 100% incorrect. One had nothing to do with the other. Monad is probably going to be a longer term project than Windows Vista, and we didn’t just decide to remove it today or yesterday.
