Discussion

A threat to users of Adobe Reader DC is opening a PDF file that contains malicious executable content. Protected mode provides a sandbox capability that prevents malicious PDF files from launching arbitrary executable files, writing to system directories or the Windows registry. This isolation of the PDFs reduces the risk of security breaches in areas outside the sandbox. Satisfies: SRG-APP-000112, SRG-APP-000206, SRG-APP-000207, SRG-APP-000209, SRG-APP-000210
