This new threat is not circulating extensively yet and updating to the latest levels of AV (plus always being careful with suspicious attachments) will help mitigate this new exposure.

Microsoft Word - Second new vulnerability and exploit

We received notification from an ISC participant that McAfee has released a dat today for protection against a buffer overflow attack in MS Word. The announcement says "Note: This vulnerability was first found through one of the samples that McAfee analyzed, and this vulnerability differs from the "Microsoft Word 0-Day Vulnerability I" that was published on December 5, 2006.".

Cnet reports the possibility of a THIRD Microsoft Office flaw (Word), for which code has been published:

"Secunia and McAfee said Thursday that a buffer-overflow flaw in the word-processing application could crash a computer and ultimately let an outsider run code on a vulnerable PC."

See the article by Dawn Kawamoto:


Whereof one cannot speak, thereof one should be silent.
