Microsoft just released preview of the April 2012 Security Bulletin. It looks like this one will have six bulletins — four of them for critical issues — and will address a total of 11 vulnerabilities. The bulletins affect all versions of Windows, Internet Explorer and Microsoft Office, plus some of Microsoft’s developer tools. One of the important bulletins is rated important, but allows Remote Code Execution on that platform, probably using a maliciously crafted input file as the attack vector. Another bulletins also deserves attention, at least for Office 2007 SP2 users.”]
