Adobe Security Updates, April 2012

Adobe has released its quarterly security updates, and issued a new Security Bulletin [APSB12-08] for its Reader software for Windows, Mac OS X, and Unix/Linux, and for its Acrobat software for Windows and Mac OS X.   The new versions of the software address four security vulnerabilities, identified in the Security Bulletin; Adobe characterizes these as Critical updates.   (More detailed information is in the Security Bulletin.)  The affected versions of the software are:

  • Adobe Reader X (10.1.2) and earlier 10.x versions for Windows and Macintosh
  • Adobe Reader 9.5 and earlier 9.x versions for Windows and Macintosh
  • Adobe Reader 9.4.6 and earlier 9.x versions for Linux
  • Adobe Acrobat X (10.1.2) and earlier 10.x versions for Windows and Macintosh
  • Adobe Acrobat 9.5 and earlier 9.x versions for Windows and Macintosh

For Reader X or Acrobat X, the new version is 10.1.3.  For users of 9.x versions of Reader, the new version is 9.5.1.

Users of Reader or Acrobat on Windows or Mac OS X can get the new version using the product’s built-in update mechanism (Help / Check for Updates).  Alternatively, you can download the new version of Reader for Windows or Mac OS X.  Download instructions for Acrobat are in the Security Bulletin [APSB12-08]

Linux users can download (via FTP)  the new version of Reader here; there are .deb and .rpm packages available, as well as a tarball.

Because Reader is so widely installed, across all platforms, it is (like Java) an attractive target for attackers.  I recommend updating your systems as soon as you conveniently can.
