Microsoft has released details of July’s Patch Tuesday, which includes a fix for a critical flaw in Internet Explorer 9 that could let hackers take control of machines and install malware.
In total, Microsoft will be issuing nine bulletins, three of which are rated as critical and related to remote code execution. The remaining fixes are rated as important. The fixes cover 16 vulnerabilities and address flaws in Windows, Office, SharePoint and Office for the Mac.
The fix for IE9 is interesting, as Microsoft generally patches its browser only every two months. Another fix for IE9 was pushed out last month, suggesting Microsoft has discovered a potentially serious issue.
Perhaps most significantly however is the updates Microsoft is rolling out to the Windows Update process itself. This follows on from the revelation that the Flame virus was able to spoof a Microsoft digital certificate, fooling PCs into believing it was legitimate software and allowing it to install via Windows Update.
