Die Already! Adobe Patches Another Zero Day Security Exploit Used By Chinese Hackers

Adobe's Flash Player has more holes than Swiss cheese, only Swiss cheese doesn't leave you vulnerable to hacker attacks. Flash Player often does, and yet again, there's a zero-day exploit that could allow an attacker to take control of an affected system. The discovered vulnerability and its severity has led to Adobe releasing an out-of-band security patch.

This latest zero-day annoyance affects Flash Player and earlier versions for Windows and Macintosh, Flash Player Extended Support Release version and earlier 13.x versions for Windows and Macs, and Flash Player and earlier 11.x versions for Linux.

"Adobe is aware of reports that CVE-2015-3113 is being actively exploited in the wild via limited, targeted attacks. Systems running Internet Explorer for Windows 7 and below, as well as Firefox on Windows XP, are known targets," Adobe said.
