As part of Microsoft's monthly Patch Tuesday, the devices and services giant will be rolling out fourteen patches for various vulnerabilities. Four of those patches are for Windows 8 and three are for Windows RT. These security patches are part of September 2013's Patch Tuesday, which rolls out today.
Windows 8 will see one critical update affecting Internet Explorer 10 and three important updates dealing with Remote Code Execution and Elevation of Privileges. Windows RT, on the other hand, will see the same critical update addressing Internet Explorer 10, along with two important updates.
The rest of the security patches affect Office 2007, Office 2010, and Office 2013. Windows Server 2003 and Windows XP both receive updates as well, along with Windows 7 and Windows Vista.
Microsoft will be rolling out these security fixes later today, so keep an eye on Windows Update! Microsoft is also expected to roll out a firmware update for the Surface RT and/or Surface Pro later today.
