Microsoft is distributing six security patches as part of its scheduled monthly patching cycle.
For June, there are four “critical” patches, one “important” patch, and one “moderately important” fix.
The critical patches address vulnerabilities in the Windows Schannel Security Package, the Internet Explorer browser, Outlook Express and Windows Mail, and the Win32 API.

All these patches prevent remote code execution by hackers, said Microsoft. The “important” patch also prevents remote code execution in Microsoft Visio, and the moderately important fix prevents information disclosure in the Windows Vista OS.
