Critical Office, Windows fixes coming next week

May's installment of Patch Tuesday is coming next week and here's what we can expect, according to the folks at Microsoft:

• Two Microsoft Security Bulletins affecting Microsoft Windows. The highest Maximum Severity rating for these is Critical. These updates will require a restart.
  
• Three Microsoft Security Bulletins affecting Microsoft Office. The highest Maximum Severity rating for these is Critical. These updates may require a restart.
  
• One Microsoft Security Bulletin affecting Microsoft Exchange. The highest Maximum Severity rating for these is Critical. These updates will not require a restart.
  
• One Microsoft Security Bulletin affecting CAPICOM and BizTalk. The highest Maximum Severity rating for these is Critical. These updates will not require a restart.

There are currently a number of unpatched Office bugs floating around and one of the "critical" Windows bulletins is likely to contain a fix for the Windows DNS RPC vulnerability that is being used in exploits. Stay tuned.
