Microsoft November 2005 patch day

That most wonderful day of the month has come when we get an idea of what vulnerabilities we may see exploited…. Seriously, if you run Windows, go to or ensure you have automatic updates if at all possible. This months most critical update relates to a vulnerability in the way windows renders (draws) images. It appears that an attacker could design a web page with images in such a way as to run arbitrary (anything they want) code (programs) on the victims computer, alter or view data, or simply control the machine (creating/removing user accounts, etc.)

The update applies to XP, 2000, and 2003. More detailed analysis can be found at I can only wonder how long before this is seen as a vector of attack for either a virus, or spyware installer.

There is also some coverage at the sunbeltblog. This basically sums up as, the vulnerability is with the gdi (graphical device interface) rendering of wmf (windows metafile) images. The image could come from a web page, html email, microsoft office document or a chat. Full disclosure summary here, and last but certainly not least eEye is credited with discovery of the vulnerability.
