Adobe has blocked another critical 0-day vulnerability in Adobe Flash Player 18.104.22.1686 and earlier versions for Mac and Windows with new security updates, updating Flash Player to version 22.214.171.1245.

The new Adobe Flash Player comes only a week after two other 0-Day vulnerabilities in Flash were discovered to have been exploited by the Angler Exploit Kit. Those vulnerabilities were patched with Flash Player 184.108.40.2066, which is now an outdated, vulnerable version of Adobe software.

According to Adobe, “Successful exploitation could cause a crash and potentially allow an attacker to take control of the affected system. […] [T]his vulnerability is being actively exploited in the wild via drive-by-download attacks against systems running Internet Explorer and Firefox on Windows 8.1 and below.”
Users of Adobe Flash Player for Mac and Windows should update to Adobe Flash Player 126.96.36.1995 (14.9 MB) immediately. Adobe said the company is working with their distribution partners to make the update available in Google Chrome and Internet Explorer 10 and 11.
