The updates are pushed out in response to recent revelations that a hacker compromised Dutch certificate authority (CA) DigiNotar (now under control of the Dutch government). The DigiNotar Qualified CA root certificate is part of the Adobe Approved Trust List (AATL) program.
The AATL is designed to make it easier for authors to create digitally signed PDF files that are trusted automatically by Adobe Reader and Acrobat versions 9 and above, and includes many certificates from around the world.
Based on the nature of the breach, Adobe is now taking the action to remove the DigiNotar Qualified CA from the Adobe Approved Trust List. This update will be published Tuesday, September 13.
The issue affects:
- Adobe Reader X (10.1) and earlier 10.x versions for Windows and Macintosh
- Adobe Reader 9.4.5 and earlier 9.x versions for Windows and Macintosh
- Adobe Reader 8.3 and earlier 8.x versions for Windows and Macintosh
- Adobe Acrobat X (10.1) and earlier 10.x versions for Windows and Macintosh
- Adobe Acrobat 9.4.5 and earlier 9.x versions for Windows and Macintosh
- Adobe Acrobat 8.3 and earlier 8.x versions for Windows and Macintosh.
