Yesterday Adobe released security updates for Adobe Flash Player 184.108.40.206 and earlier versions for Windows and Macintosh, and Adobe Flash Player 220.127.116.115 and earlier versions for Linux. Users running the earlier versions are susceptible to a vulnerability that gives attackers remote control of their computers.
Researchers from Kaspersky Labs reported the bug. The company said Adobe is aware of reports that an exploit for this vulnerability “exists in the wild.”
To verify which Flash version is installed on your system, visit Adobe’s About Flash Player page or right-click on Flash content and choose “About Adobe Flash Player” from the menu. Adobe says Flash Player plugins installed with Google’s Chrome browser or Microsoft’s Internet Explorer 10 or 11 will be updated automatically.
