Critical security vulnerabilities in Adobe Acrobat and Adobe Reader have been identified and Adobe has issued a security advisory. These are being actively exploited in the wild by sending users malicious PDF files.
This affects users of Linux systems, Macs, or Windows.
Adobe is recommending users enable Protected View via Edit > Preferences > Security (Enhanced).
Unfortunately, this security feature is not enabled by default. Thanks, Adobe.
This is one of the many reasons we recommend using SumatraPDF (via Ninite.com). It is lightweight, functional, and it’s one additional layer of protection against attacks.
For clients on our System Monitoring w/ Patch Management service, we will be addressing this issue for you.
