Adobe recently released a security bulletin announcing an emergency update that affects all versions of its Flash player for an exploit. Fortunately for Mac users, the exploit seems to be mainly targeting Windows PCs running Microsoft’s Internet Explorer. Adobe has given Mac users a priority rating of a "2" along with Linux and Android users (for both 4.x, 3.x, and 2.x). The Windows OS was the only platform that received a priority rating of a "1."
The whole issue was dubbed as “object confusion vulnerability” with the bug tricking a user into opening a malicious file sent in an email message. The file can cause flash to crash, potentially giving the attacker control of the affected PC. The issue was first reported by Microsoft Vulnerability Research and the bug was found residing in Flash Player code for Windows, Mac, Linux, and even the Android platform, although Adobe is claiming that the exploit being used only targets Internet Explorer for Microsoft’s operating system. Users who installed Flash on Google Chrome are not affected as the browser is updated automatically.
Adobe recommends users of Adobe Flash Player 18.104.22.168 and earlier versions for Windows, Macintosh and Linux update to Adobe Flash Player 22.214.171.124," Adobe said in the bulletin. "Users of Adobe Flash Player 126.96.36.199 and earlier versions on Android 4.x devices should update to Adobe Flash Player 188.8.131.52. Users of Adobe Flash Player 184.108.40.206 and earlier versions for Android 3.x and earlier versions should update to Flash Player 220.127.116.11.
