The Adobe Acrobat and Reader 8.1.2 Security Update 1 addresses a buffer overflow security vulnerability as described in Adobe Security Bulletin APSB08-15. This update also addresses a privilege escalation issue on Adobe Reader for UNIX (not present in Windows or Macintosh) as described in Adobe Security Bulletin APSA08-02. Adobe always recommends that you install the latest security updates.
Note: This Security Update can be applied only to Adobe Acrobat and Reader versions 8.1.2 on Windows and Macintosh. Adobe Reader for UNIX 8.1.2 Security Update 1 is a full installer and therefore, does not have a previous version requirement.
