Adobe has rolled-out an urgent out-of-band update for a critical remote code-execution vulnerability in its popular Flash Player that is currently being exploited by hackers. The vulnerability allows an attacker to execute arbitrary code due to a weakness in the way a dereferenced pointer to memory is handled. Adobe rated the vulnerability as critical and recommended users and administrators to update their software on Windows, Mac OS X and Linux systems to the latest iteration as soon as possible. Microsoft will soon be releasing security updates for Internet Explorer 10 and 11 and Google will be releasing for Chrome.
