Microsoft is going patch crazy! In addition to the just released Exchange 2007 update, the company is also readying a superpatch for Office and Windows. The company said it will issue four security updates next week, only one of which is pegged as critical, to patch 22 vulnerabilities in Windows and Visio 2003.

This update is smaller than June’s but still includes tons of fixes and the like. The bugs-per-bulletins ratio, however, is the highest for the year.

“I think we’ll see one bulletin with a very high number of vulnerabilities,” said Andrew Storms, director of security operations at nCircle Security. “We’ve seen that happen several times this year, most recently last month when it patched eight bugs in Excel with one update.”
