The Zero Day Initiative has published a new and unpatched IE 0-Day that was originally reported to them (and by extension, Microsoft) in October 2013.  In essence, a victim has to go to a crafted webpage that takes advantage of handling of CMarkup objects which ultimately can be used to execute code with the permissions of the web browser process.  Microsoft says the EMET will mitigate this vulnerability and at least Tipping Point claims protection with their devices.  At this point, there is no indication that it is being used in the wild.  The interesting thing here is the timeline between initial report and there being no patch.

This diary will be updated as the situation warrants.
