Microsoft April Patch Tuesday Advance Notification

Microsoft is expecting to release a total of 9 bulletins, 2 of which are critical, and the rest important. One of the critical bulletins affects Windows and Internet Explorer, so we expect the usual Internet Explorer cumulative patch, maybe fixing some of the "pwn2own" vulnerabilities discovered during CanSecWest.

Otherwise it is a lot of "the usual" with Windows, Office and "Server Software" (Sharepoint and Groove) patches. The one that sticks out a bit is the bulletin fixing "Security Software". It will patch a vulnerability in Windows Defender on Windows 8 and RT. 

So overall an average patch Tuesday.
