Flash Player workaround available for "Clickjacking" issue
Adobe Flash Player 18.104.22.168 and earlier
Adobe is aware of recently published reports of a ‘Clickjacking’ issue in multiple web browsers that could allow an attacker to lure a web browser user into unknowingly clicking on a link or dialog. It has been determined that this potential "Clickjacking" issue affects Adobe Flash Player. Adobe is working to address this issue in an upcoming update to Flash Player.
To prevent this potential issue, customers can change their Flash Player settings as follows:
- Access the Global Privacy Settings panel of the Adobe Flash Player Settings Manager at the following URL: http://www.adobe.com/support/documen...manager02.html
- Select the "Always deny" button.
- Select ‘Confirm’ in the resulting dialog.
- Note that you will no longer be asked to allow or deny camera and / or microphone access after changing this setting. Customers who wish to allow certain sites access to their camera and / or microphone can selectively allow access to certain sites via the Website Privacy Settings panel of the Settings Manager at the following URL: http://www.adobe.com/support/documen...manager06.html.
IT Administrators can change the AVHardwareDisable value in client mms.cfg files from 0 to 1 to disable client Flash Player camera and microphone interactions. For more information on the mms.cfg file and AVHardwareDisable, please refer to page 57 of the Adobe Flash Player Administration Guide: http://www.adobe.com/devnet/flashpla...de.pdf#page=57
Adobe is working to address the issue in an upcoming Flash Player update, scheduled for release before the end of October. Further details will be published on the Adobe Security Bulletin page at http://www.adobe.com/support/security
