URGENT Security Alert: Emergency Update Released by Microsoft
Microsoft has released an emergency update to their Malware Protection Engine because of an extremely serious vulnerability which allows attackers to gain full access to Windows computers by running executing code they provide with the authorities of the Malware Protection Engine. If you use Windows and do not have your computer set to update automatically, you should install the fix immediately.
As you might know, Microsoft packages security fixes together and ships them once a month unless an extremely serious vulnerability is discovered. In those cases, an “out-of-band” fix is released. This is one of those cases. If it is serious enough for Microsoft to release an out-of-band fix just days before their regular December fixes, it is definitely serious enough for you to install it promptly.
