Adobe will release an emergency Flash Player update as soon as Thursday, patching a critical vulnerability that is being publicly attacked. The vulnerability is in version 21.0.197 and earlier for Windows, Mac OS X, Linux and Chrome OS. French researcher Kafeine, who publishes updates on his personal site on exploit kits, is one of three researchers credited with disclosing the bug to Adobe along with FireEye s Genwei Jiang and Google’s Clement Lecigne. Adobe said successful exploitation could cause a crash and allow an attacker to take control of the affected system.
