Adobe Flash Vulnerability

The hacking of an intrusion and surveillance technology firm last Sunday led to a public information dump including proof-of-concept, attack code, and documentation for a previously undisclosed critical security vulnerability in all versions of Adobe Flash Player. Since that time, researchers have determined that the leaked exploit has been integrated into several widely-used exploit kits.

Late this morning Adobe released an update to patch this vulnerability on Windows, Macintosh, and Linux systems. Many, if not most, installations of Flash Player on Windows and Mac OS will receive this update automatically via the update mechanisms built into Flash Player, Google Chrome, and Internet Explorer. Users of Adobe Flash Player for Linux should visit the Adobe Flash Player Download Center at to update their software.
How do I know if this impacts me?
Unless your installation of Flash Player has already updated itself, it is extremely like that your installation is vulnerable. You can check your version of Flash Player by visiting Adobe's About Flash Player page at The page will detect your version of Flash and display it on the page under "Version Information". If your version is or earlier (for Windows, Macintosh and Chrome on all OSes) or or earlier on Linux, you're vulnerable.
What do I need to do in order to get this update?
Most users of Flash Player on Windows and Mac computers will receive the update automatically. To confirm that your system is set to receive updates or, if you'd like, to manually check for the update please do the following:
  1. Open the Control Panel (in Windows) or System Preferences (in Mac OS).
  2. Double-click Flash Player to open that program's settings window.
  3. Click the "Advanced" tab.
  4. In that tab, under "Updates", you will have one of three options checked (these will be grayed out for some Windows users):
    • Allow Adobe to install updates (recommended)
    • Notify me to install updates
    • Never check for updates (not recommended)
If your system's settings are to "Allow Adobe to install updates (recommended)", you'll receive the update automatically in the background. If your system is set to "Notify me to install updates", you will receive a notification information you there is an update available. You will need to click the button in that notification to tell the software to update.
If your system is set to "Never check for updates (not recommended)", you'll need to update manually. You can click "Check Now" in that same tab to have the software check for updates and begin the installation process or you can visit the Adobe Flash Player Download Center at to download and install the update.
What about Adobe Flash Player for Linux?
Users of Adobe Flash Player for Linux should visit the Adobe Flash Player Download Center at to download and install the update.
