Adobe has released security updates for Adobe Acrobat and Reader for Windows and Macintosh. These updates address critical vulnerabilities that could potentially allow an attacker to take control of the affected system.

Note: As outlined in this blog post, Adobe Acrobat X and Adobe Reader X are no longer supported.  Adobe recommends users install Adobe Acrobat DC and Adobe Acrobat Reader DC for the latest features and security updates.

For questions regarding Acrobat DC, please visit the Acrobat DC FAQ page. For questions regarding Acrobat Reader DC, please visit the Acrobat Reader DC FAQ page.   

Adobe recommends users update their software installations to the latest versions by following the instructions below.

The latest product versions are available to end users via one of the following methods: 

• Users can update their product installations manually by choosing Help > Check for Updates. 
• The products will update automatically when updates are detected without requiring user intervention. 
• The full Acrobat Reader installer can be downloaded from the Acrobat Reader Download Center. 

For IT administrators (managed environments): 

• Download the enterprise installers from ftp://ftp.adobe.com/pub/adobe/, or refer to the specific release note version for links to installers. 
• Install updates via your preferred methodology, such as AIP-GPO, bootstrapper, SCUP/SCCM (Windows), or on Macintosh, Apple Remote Desktop and SSH.
