In order to address critical vulnerabilities that could potentially allow an attacker to take control of the affected system, Adobe has released a security update for its Flash player.
The company issued the update last week for systems including Mac, Windows, Linux and Chrome OS. If your Mac has version 18.104.22.168 or earlier, you should install the update as soon as possible. The update can be found here.
Adobe notes, “Users of Flash Player 11.2.x or later for Windows, or Flash Player 11.3.x or later for Macintosh, who have selected the option to ‘Allow Adobe to install updates’ will receive the update automatically. Users who do not have the ‘Allow Adobe to install updates’ option enabled can install the update via the update mechanism within the product when prompted.”
The update details include type confusion, integer overflow and use-after-free vulnerabilities that could lead to code execution, as well as buffer overflow and memory corruption vulnerabilities.
As MacRumors has pointed out, macOS Sierra disables Adobe Flash by default.
