HTTP: OpenAction JavaScript in Adobe PDF

This signature detects a OpenAction JavaScript parameter in PDF files sent via HTTP. The OpenAction parameter defines what action should occur when the document is opened. By specifying that a JavaScript program be run, an attacker could write malicious JavaScript that would execute when a user tried to read the PDF file. Some known cases resulted in remote arbitrary code execution.
