Woke up this morning to find a Microsoft patch for WMF had been downloaded, and was ready to install. If you want to read about it, or need to update manually, see Microsoft Security Bulletin MS06-001
In the release note, Microsoft says:
Microsoft originally planned to release the update on Tuesday, Jan. 10, 2006, as part of its regular monthly release of security bulletins, after testing for quality and application compatibility was complete. However, testing has been completed earlier than anticipated and the update is ready for release. In addition, Microsoft is releasing the update early in response to strong customer sentiment that the release should be made available as soon as possible.
Microsoft's monitoring of attack data continues to indicate that the attacks are limited and are being mitigated both by Microsoft's efforts to shut down malicious Web sites and by up-to-date signatures from anti-virus companies.
All in all, WMF seems to have had very little impact. But it could have turned out much much worse.....
