CVE number: CVE-2012-0779

Platform: All Platforms
Summary

Adobe released security updates for Adobe Flash Player 11.2.202.233 and earlier 
versions for Windows, Macintosh and Linux, Adobe Flash Player 11.1.115.7 and 
earlier versions for Android 4.x, and Adobe Flash Player 11.1.111.8 and earlier 
versions for Android 3.x and 2.x. These updates address an object confusion 
vulnerability (CVE-2012-0779) that could cause the application to crash and 
potentially allow an attacker to take control of the affected system.
There are reports that the vulnerability is being exploited in the wild in 
active targeted attacks designed to trick the user into clicking on a malicious 
file delivered in an email message. The exploit targets Flash Player on 
Internet Explorer for Windows only.

Adobe recommends users of Adobe Flash Player 11.2.202.233 and earlier versions 
for Windows, Macintosh and Linux update to Adobe Flash Player 11.2.202.235. 
Flash Player installed with Google Chrome was updated automatically, so no user 
action is required. Users of Adobe Flash Player 11.1.115.7 and earlier versions 
on Android 4.x devices should update to Adobe Flash Player 11.1.115.8. Users of 
Adobe Flash Player 11.1.111.8 and earlier versions for Android 3.x and earlier 
versions should update to Flash Player 11.1.111.9.

Affected software versions

    Adobe Flash Player 11.2.202.233 and earlier versions for Windows, Macintosh 
      and Linux operating systems
    Adobe Flash Player 11.1.115.7 and earlier versions for Android 4.x, and 
      Adobe Flash Player 11.1.111.8 and earlier versions for Android 3.x and 
      2.x

To verify the version of Adobe Flash Player installed on your system, access 
the About Flash Player page, or right-click on content running in Flash Player 
and select "About Adobe (or Macromedia) Flash Player" from the menu. If you use
multiple browsers and did not choose to receive updates silently (Windows users 
only at this time), perform the check for each browser you have installed on 
your system.

To verify the version of Adobe Flash Player for Android, go to Settings > 
Applications > Manage Applications > Adobe Flash Player x.x.

Solution

Adobe recommends users update their software installations by following the 
instructions below:

Adobe recommends users of Adobe Flash Player 11.2.202.233 and earlier versions 
for Windows, Macintosh, and Linux update to the newest version 11.2.202.235 by 
downloading it from the Adobe Flash Player Download Center. Windows users of 
Flash Player 11.2.x who have selected the silent update option will receive the 
update automatically. Windows users who do not have the silent update option 
enabled and users of Adobe Flash Player 10.3.x or later for Macintosh can 
install the update via the update mechanism within the product when prompted. 
Flash Player installed with Google Chrome was updated automatically, so no user 
action is required.

For users who cannot update to Flash Player 11.2.202.235, Adobe has developed a 
patched version of Flash Player 10.x, Flash Player 10.3.183.19, which can be 
downloaded here.

Users of Adobe Flash Player 11.1.115.7 and earlier versions on Android 4.x 
devices should update to Adobe Flash Player 11.1.115.8 by browsing to Google 
play on an Android device. Users of Adobe Flash Player 11.1.111.8 and earlier 
versions for Android 3.x and earlier versions should update to Flash Player 
11.1.111.9 by browsing to Google play on an Android device.
