Adobe Systems released a critical security update for Flash Player that fixes 12 security vulnerabilities, but pushed back its planned patches for Reader and Acrobat by a week.
The Flash Player updates, available for Windows, Mac and Linux, address nine vulnerabilities that could lead to remote code execution and three that can allow attackers to bypass security features, including memory address randomization and the same-origin policy.
Windows and Mac users should update to Flash Player 18.104.22.168 and Linux users to Flash Player 22.214.171.1246, Adobe said in a security advisory. Users of the Flash Player Extended Support release should update to version 126.96.36.199, the company said.
The Flash Player versions bundled with Google Chrome, Internet Explorer 10 and Internet Explorer 11 will be updated automatically through the update mechanisms of those browsers.
The company also released new versions of Adobe AIR for Windows and Android, because the runtime also includes Flash Player. The patched Adobe AIR version for Windows is 188.8.131.52 and for Android 184.108.40.206.
Adobe also planned to release security updates Tuesday for Reader and Acrobat as part of its patch cycle, which is aligned with Microsoft's. However, the company rescheduled those updates for next week in order "to address issues identified during routine regression testing."
