Adobe Flash Vulnerabilities

   Original release date: September 20, 2010
   Last revised: --
   Source: US-CERT


Systems Affected

     * Adobe Flash Player 10.1.82.76 and earlier versions
     * Adobe Flash Player 10.1.92.10 for Android
     * Adobe Reader 9.3.4 and earlier 9.x versions

     Other Adobe products that support Flash may also be vulnerable.


Overview

   According to Adobe Security Bulletin APSB10-22 there are
   vulnerabilities in Adobe Flash. These vulnerabilities affect Flash
   Player, Reader, and possibly other products that support Flash. A
   remote attacker could exploit these vulnerabilities to execute
   arbitrary code.


I. Description

   Adobe Security Bulletin APSB10-22 describes vulnerabilities in
   Adobe Flash that affect Flash Player. These vulnerabilities may
   also affect other products that independently support Flash, such
   as Adobe Reader, Acrobat, Photoshop, Photoshop Lightroom, Freehand
   MX, and Fireworks.

   An attacker could exploit these vulnerabilities by convincing a
   user to open specially crafted Flash content. Flash content is
   commonly hosted on a web page, but it can also be embedded in a PDF
   and other documents or provided as a stand-alone file.


II. Impact

   If a user opens specially crafted Flash content, a remote attacker
   may be able to execute arbitrary code.


III. Solution

   Update Flash


   Adobe Security Bulletin APSB10-22 recommends updating to Flash
   Player 10.1.85.3 for Windows, Mac OS, Linux, and Solaris and Flash
   Player 10.1.95.1 for Android.  However, products like Adobe Reader
   with embedded Flash will require their own security updates.

   To reduce your exposure to these and other Flash vulnerabilities,
   consider the following mitigation technique.

   Disable Flash in your web browser


   Uninstall Flash or restrict which sites are allowed to run Flash.
   To the extent possible, only run trusted Flash content on trusted
   domains. For more information, see Securing Your Web Browser.

   Additional workarounds are available in US-CERT Vulnerability Note
   VU#275289.
