Description
A threat to users of Adobe Reader DC is opening a PDF file that contains malicious executable content. Protected view restricts Adobe Reader DC functionality, within a sandbox, when a PDF is opened from an untrusted source. 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
