| Description | ||||
| Flash has a long history of vulnerabilities. Although Flash is no longer provided with Acrobat, if the system has Flash installed, a malicious PDF could execute code on the system. Configuring Flash to run from a privileged location limits the execution capability of untrusted Flash content that may be embedded in the PDF. | ||||
