8 Security Bulletins were released – 3 Critical, 5 Important, and 0 Moderate
This Month In Brief
We have not uncovered any widespread problems with any of these patches and are releasing all of them.
MS13-090 is a zero day vulnerability reported a few days ago. This is an update for ActiveX Kill Bits and is already being actively exploited in the wild. Microsoft was already aware of the problem and had created and tested the fix. Make sure MS13-090 gets installed along with MS13-088 (a cumulative IE update) to Internet Explorer fully secured.
Also of interest is a second zero day flaw which remains unpatched. This vulnerability involving how Office handles .TIFF graphics files. Microsoft Security Advisory (2896666) – http://technet.microsoft.com/en-us/security/advisory/2896666 There is some debate over the urgency of this but we expect Microsoft to release and out-of-band before December’s Patch Tuesday. We will release the patch as soon as it becomes available as is our policy for out-of band patches.
No out-of-band updates were released during the last month.
