A posting  from Naked Security:

Midsummer Patch Tuesday (or midwinter, depending on your latitude) takes place on Tuesday 11 June 2013.

As you probably already know, Microsoft publishes an official Advance Notification each month to give you early warning of what’s coming.

These early notifications generally don’t give any details, summarising only the basics, such as:

• The number of Bulletins (read: security patches) you’ll get.
• The severity levels (read: urgency) of the patches.
• The products or components being fixed.
• Whether a reboot is required.

And June’s answers, as briefly as possible, are:

• Five.
• One critical and four important.
• Windows and Office.
• Yes.

So it sounds on the surface like a light month, with only two remote code execution (RCE) vulnerabilies to worry about.
