Adobe is releasing an emergency patch for Flash after spotting a critical flaw that is now being "actively exploited" in the wild.
Users of Windows 7 and Windows XP with Flash Player version 188.8.131.526 and earlier are vulnerable to an externally forced shutdown that can be used to mask remote code execution on a target system. The threat was deemed serious enough to issue the patch out of schedule and Adobe hopes to have it out by April 7.
If you're running a version of Flash later than 184.108.40.206 then a mitigation for the attack is already in place.

Edit: Not sure why the article notes 220.127.116.11 when the adobe Advisory notes 18.104.22.168 and earlier is vulnerable.
