Patch Tuesday is also Patch Tuesday and the updated Stuxnet patch is one of 14 bulletins released by Microsoft. Five of the bulletins are rated critical by Microsoft, and include another Internet Explorer rollup and a patch for the recently disclosed FREAK attack. Microsoft also released an advisory announcing that SHA-2 code signing support has been added to Windows 7 and Windows Server 2008 R2. The highest profile bulletin, however, is MS15-020 which resolves some issues left behind by the original patch, CVE-2010-2568, released in August 2010.
