RELATED:
All four critical bulletins will patch remote code execution vulnerabilities. While Bulletins 1 through 3 all address exploits in Windows, the first and third also target those in Internet Explorer Versions 6 through 9 and the .NET framework, respectively. Bulletin 4, meanwhile, addresses critical vulnerabilities in SQL , developer tools Visual FoxPro and Visual Basic, and Office versions 2003 through 2010.
ROUNDUP:
The remaining two patches were both rated "important" and address vulnerabilities in Office and Forefront United Access Gateway.
Qulays CTO Wolfgang Kandek says the Internet Explorer bulletin is likely to be treated with the most importance among users, "just because everyone uses the browser every day and knows that attacks today go against some browser vulnerabilities."
