In addition to the IE issue reported, Juha-Matti (thanks) pointed us to the blog entry at the MSRC which points to the following issue.  http://www.microsoft.com/technet/security/advisory/960906.mspx

This issue affects the wordpad text converter for word 97 on a number of operating systems.  XP SP3, Vista and Server 2008 are not vulnerable. 

Microsoft is investigating some targeted attacks.  If you have captures of samples relating to this let us know.

This issue is NOT addressed by any of the December patches.
