I wanted to make you all aware that Microsoft has released a very important patch today (Aug. 2, 2010). This patch fixes a major flaw in all Microsoft operating systems (see below) dating back to Windows 2000 commonly referred to as the “Windows Shortcut Exploit”. This flaw was discovered in late July and Microsoft has responded quickly and are providing this update out of their typical second Tuesday of the month patch cycle.
I am recommending that you install this patch. If you have windows updates turned on (and you should) you will get the patch automatically, if not, you can download it and install it from the Windows Update web site, it is the Security update with the (KB2286198) designation. The patch will only be issued for actively supported products, Windows XP w/service pack 3, Vista, Windows 7, Server 2003 and 2008. If you have an older unsupported version of windows, the security company Sophos has issued the “Windows Shortcut Exploit Protection Tool”. I would urge you to install it.
