To disable JavaScript in Adobe Reader:

1. Open Adobe Acrobat Reader.
   
2. Open the Edit menu.
   
3. Choose the Preferences... option.
   
4. Choose the JavaScript section.
   
5. Uncheck the Enable Acrobat JavaScript check box.
   

Disabling JavaScript will not resolve the vulnerabilities, it will only disable the vulnerable JavaScript component. When JavaScript is disabled, Adobe Reader and Acrobat prompt to re-enable JavaScript when opening a PDF that contains JavaScript.
