Updating a pdf document software

While Java Script is designed without direct access to the file system to make it "safe", vulnerabilities have been reported for abuses such as distributing malicious code by Acrobat programs.

As a workaround for this issue, US-CERT recommended disabling Java Script in the affected Adobe products, canceling integration with Windows shell and web browsers (while carrying out an extended version of de-integration for Internet Explorer), deactivating Adobe indexing service and avoiding all PDF files from external sources.

In April 2015, Adobe introduced the Adobe "Document Cloud," along with the first of several applications with "DC" at the end of the name.

One of the main goals was to have all of a user's PDFs available on any of the user's devices, such as editing a PDF on an i Pad and then later retrieving it on a PC.

The UI had major changes with the introduction of Acrobat DC in 2015, which supports Windows 7 and later, and OS X 10.9 and later.

The basic Acrobat Reader, available for several desktop and mobile platforms, is freeware; it supports viewing, printing and annotating of PDF files.This functionality allows a PDF document creator to include code which executes when the document is read.Malicious PDF files that attempt to attack security vulnerabilities can be attached to links on web pages or distributed as email attachments.There have been reports of these vulnerabilities being exploited to trick Windows users into clicking on a malicious PDF file delivered in an email message.Adobe recommended users update their product installations.
