Not that this is anything special, its the remediation steps that caught my eye. Also the number of platforms affected.

Just delete the lib!

Adobe Reader and Acrobat 9.x - Windows
          Deleting, renaming, or removing access to the authplay.dll file that ships with Adobe Reader and
          Acrobat 9.x mitigates the threat for those products, but users will experience a non-exploitable
          crash or error message when opening a PDF file that contains Flash (SWF) content.

The authplay.dll that ships with Adobe Reader and Acrobat 9.x
 for Windows is typically located at C:\Program Files\Adobe\Reader
9.0\Reader\authplay.dll for Adobe Reader or C:\Program
Files\Adobe\Acrobat 9.0\Acrobat\authplay.dll for Acrobat.

Adobe Reader 9.x - Macintosh 
          1) Go to the Applications->Adobe Reader 9 folder.
2) Right Click on Adobe Reader.
3) Select Show Package Contents.
4) Go to the Contents->Frameworks folder.
          5) Delete or move the AuthPlayLib.bundle file.

Acrobat Pro 9.x - Macintosh
          1) Go to the Applications->Adobe Acrobat 9 Pro folder.
2) Right Click on Adobe Acrobat Pro.
3) Select Show Package Contents.
4) Go to the Contents->Frameworks folder.
          5) Delete or move the AuthPlayLib.bundle file.

Adobe Reader 9.x - UNIX 
          1) Go to installation location of Reader (typically a folder named Adobe).
          2) Within it browse to Reader9/Reader/intellinux/lib/ (for Linux) or Reader9/Reader/intelsolaris/lib/ (for Solaris).
        3) Remove the library named "libauthplay.so.0.0.0."

NIST has a little more information.

I really just want to know what the purpose of the DLL file is, but that seems to be hard to find.
