Adobe released an emergency patch for a critical vulnerability affecting Flash Player for Windows, Linux and OS X, the exploitation of which can result in an attacker gaining remote control of the victims’ systems.
According to the Adobe security advisory, the flaw is under active exploitation. In terms of details of the vulnerability, Adobe is just crediting its discovery to researchers Alexander Polyakov and Anton Ivanov of Kaspersky Lab. No details about the ongoing attack was immediately available.
A post published on Monday on Kaspersky Lab’s Securelist blog said their researchers uncovered a new sophisticated cyber espionage operation that, among other things, was able to compromise Macs and computers running Linux.
It seems probable that the Flash flaw is among the ones leveraged by the attackers, but we won’t know for sure until more details about this operation end up unveiled next week at the Kaspersky Security Analyst Summit 2014 in the Dominican Republic.
Don’t wait to implement the fix. If you use Adobe Flash Player 126.96.36.199 and earlier versions for Windows and Macintosh or Adobe Flash Player 188.8.131.525 and earlier versions for Linux, visit Adobe’s Flash Player Download Center and pick it up.
If you use Flash embedded in Chrome or Internet Explorer, update your browser to the newest, non-vulnerable versions.
