Patch Tuesday June 2012 – IE Client Side and RDP Exposures, 27 Other Vulnerabilities
Microsoft released a set of five bulletins, patching 29 total software vulnerabilities. Multiple remote code execution holes are being patched, but the two most urgent are the Internet Explorer and Remote Desktop Protocol updates. Almost half of the 29 vulnerabilities being patched this month are maintained in versions 6, 7, 8, and 9 of Internet Explorer code, all patched with Security Bulletin MS12-037.
RDP is not enabled by default on Windows systems, but exposure to this month’s remote code execution vulnerability is a problem for many businesses around the world, as the recent activity from the Morto worm demonstrated. Updating systems with MS12-036 is a priority – including Windows 2003 installs and up to the Server Core installation of Windows Server 2008 R2 for x64-based Systems Service Pack 1. It’s rated critical, and most versions of Windows server OS are vulnerable not only to DoS attacks, but remote code execution.
For most folks, properly licensed Windows systems with Windows Updates enabled will update the software automatically over the next day or so. People can also find “Windows Updates” in their start menu and open it, then click on “Check for Updates”.
