And just in case you don't believe it's insane, check out this handy chart, which provides a matrix of the security fixes and the products they affect:

Yep, it's that time of the month. Here's the official word:

Today, as part of its routine monthly security update cycle, Microsoft is releasing 11 security bulletins to address 25 vulnerabilities: five rated Critical, five rated Important and one rated Moderate. This month's release affects Windows, Microsoft Office, and Microsoft Exchange. Additionally, the Malicious Software Removal Tool (MSRT) was updated to include Win32/Magania.

Microsoft recommends that customers deploy all security updates as soon as possible. However, Microsoft's guidance on deployment priority is that customers should consider MS10-019, MS10-026, and MS10-027 as the top priority bulletins for April.

By the way, the point of the chart above isn't high comedy, but is rather to "demonstrate the reduced impact of the April security bulletins on operating systems that have benefitted from the Security Development Lifecycle (SDL)." In other words: Newer versions of Microsoft software are not as impacted by security issues as are older versions. Fair enough.
