Microsoft released the patch today for the WMF image vulnerability, ahead of schedule. It can be downloaded from here:

http://www.microsoft.com/athome/security/update/bulletins/200601_WMF.mspx

If you are running Windows XP, Windows 2000, or Windows 2003, you should download and install the update immediately. There are exploits taking advantage of this flaw - and it involves viewing an image to become vulnerable, not downloading or running anything. Windows 98/ME users apparently are not affected by the issue, contrary to earlier reports.

Thanks Cris, I got smacked with this last week, it corrupted an instance of XP on one of my drives! Watch Out! Be Careful!

Yes that is the patch - Windows Update will find it if you need it.

hmmm... either it was already downloaded with my auto update thingy. Followed the link, it did a search and said I did not have any downloads. Either that or I did something wrong.

Technical question

Question would be... does the image parsing in the SL client use this vulnerablity? Could someone use an image in SL that triggers it?

Just thought I'd ask, was curious. :)

PS: MacOS or... UNIX. Mmmm, UNIXy goodness.

Does SL even accept WMF's?

I'm not sure, of course, but I'm also not sure what SL uses to process images, and whether or not the client uses the vulnerable code. Something for the programmers to answer, I guess.

No need to fear. The vulnerability was specifically for MS Windows .WMF files. They are not so much a graphics file like other formats in that they don't encode an image directly. They store a recording of the drawing operations needed to create the image. Someone discovered some harmful operations that could also be stored in the "recording". These operations are then executed when Windows "plays back" the WMF file to recreate the image.

Second Life doesn't transfer any content using this format at all (textures, for example, are stored as JPG2000, which is decompressed - not executed).

Definitely get the fix to protect yourself from malicious WMF files sent to you via email or downloads - but rest assured that SL is safe.

MJ, that's not the patch. That's an upgrade to Windows Update. Once you install that you need to check for updates again.

Eeek you're right, I didn't look more closely at that screen shot - good catch.

Only Microsoft would think an image that's actually a Macro (virus) was a good idea.

Or.... uummmm... postscript - for example.
From a developer's perspective, the ability to save GDI commands (not macros) (not viruses) to a file is wonderful.

From a developer's perspective - cheap shots at MS are just that - cheap.

Thanks, will try again :)

Edit: Okay, tried again and it appeared nothing happened. So, I went ahead and looked in the update history and found this... Windows XP Security Update for Windows XP (KB912919) Friday, January 06, 2006 Automatic Updates....I'm thinking that its been successfully updated.
