            Adobe Reader and Acrobat Critical Security Updates

            Adobe

            Adobe has released security updates for Adobe Reader and Acrobat XI for Windows. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.

            Release date: August 8, 2017
            Vulnerability identifier: APSB17-24
            Platform: Windows

            Update or Complete Download

            Update checks can be manually activated by choosing Help > Check for Updates.

            Note: UNcheck any pre-checked additional options presented with the update. They are not part of the software update and are completely optional.

            Enable "Protected View"

            Due to frequent vulnerabilities, it is recommended that Windows users of Adobe Reader and Acrobat ensure that Protected View is enabled.  Neither the Protected Mode or Protected View option is available for Macintosh users.

            To enable this setting, do the following:

            • Click Edit > Preferences > Security (Enhanced) menu. 
            • Change the "Off" setting to "All Files".
            • Ensure the "Enable Enhanced Security" box is checked.
