Title
Adobe Acrobat Pro XI Default Handler changes must be disabled. (Cat III impact)
Discussion
Acrobat Pro allows users to change the version of Acrobat Pro that is used to read PDF files. This is a risk if multiple versions of Acrobat are installed on the system and the other version has dissimilar security configurations or known vulnerabilities. When the Default PDF Handler is disabled, the end users will not be able to change the default PDF viewer.
