Adobe Reader Ubuntu

Adobe Acrobat Reader is a family of web services and application software which is developed by Adobe Inc. for viewing, creating, manipulating, printing, and managing Portable Document Format (short for PDF) files.

The family contains Acrobat Reader (formerly called Reader) Acrobat (formerly called Exchange) and Acrobat.com. The common Acrobat Reader is a freeware that is available for various mobile and desktop platforms.

It supports annotating, printing, and viewing PDF files. Additionally, "Premium" services are also accessible on a paid subscription. Acrobat.com aggregates the family along with the range of file hosting services and enterprise content management. The commercial proprietary Acrobat can also convert, edit, create, digitally sign, publish, export, and encrypt PDF files and it is available for macOS and Microsoft Windows only.

History of Adobe Reader

In 1993, Adobe Acrobat Reader was introduced and had to face other proprietary formats and products that focused on making digital documents:

  • DjVu via AT&T Laboratories
  • WorldView via Interleaf
  • Replica via Farallon Computing
  • Folio Views via NextPage
  • Envoy via WordPerfect Corporation
  • Common Ground via No Hands Software Inc.

Adobe has retitled the Acrobat products many times, in inclusion to splitting, merging, and discontinuing them. The given products were initially known as Acrobat Distiller, Acrobat Exchange, and Acrobat Reader. Soon, "Acrobat Exchange" became "Acrobat". "Acrobat Reader" then became "Reader" over time. Between the 3 and 5 versions, Acrobat didn't have many editions. The service, i.e., Acrobat.com, came into being and announced various web services whose titles began with "Acrobat" in 1999, but "Acrobat.com" was declined from the family name of services eventually. The Acrobat products don't have icons that show two letters on the colored rectangle, unlike almost all other products of Adobe, including the family, i.e., Adobe Creative Suite.

Document Cloud

Adobe announced the "Document Cloud" branding to signify its acceptance of the software as a service and cloud storage model in April 2015. Under this branding, programs get a "DC" suffix. In inclusion, "Reader" was returned to "Acrobat Reader". Acrobat.com was canceled because its aspects were merged into the mobile applications and desktop programs following the announcement of Document Cloud.

  • In 2015, the GUI had dominant changes with the announcement of Acrobat DC, which supports the 7 and later versions of Windows, and the 10.9 and later versions of OS X.
  • Now, version numbers are recognized by the last two-year digits of the major version, and the year and month are specified; the older version was 12, but DC Acrobat product family version examples are DC June 2016, the 15.016.20045 version, published on 2 June 2016 and Document Cloud Classic in January 2016, the 15.006.30119 version, published on 12 January 2016.
  • The Acrobat family is present in two tracks from DC 2015, the Continuous track and the actual track, now called Classic.
  • Updates are quarterly published for the Classic track and don't contain new aspects.
  • Besides, updates are more frequently issued for the Continuous track and implemented automatically and silently.

The last pre-DC release, Acrobat XI, was upgraded to the 11.0.23 version on 14 November 2017 and ended support a month earlier on 15 October 2017. Adobe published an aspect to make documents easier to understand on phones known as "Liquid Mode", along with its Sensei AI in September 2020.

Purpose of Adobe Reader

The primary function of Adobe Reader is editing, viewing, and creating PDF documents. Also, it can import famous image and document formats and store them as PDF. It is possible for importing the output of a scanner, Windows clipboard contents, or a website.

However, when a document of PDF is created, its original flow and organization can't be modified meaningfully due to the nature of the PDF. Adobe Reader is to change the contents of images and paragraphs, but doing so doesn't recheck the entire document for accommodating a shorter or longer document. Acrobat can change the order of the PDF pages, crop them, manipulate hyperlinks, add comments, digitally sign PDF files, edit many PDF file parts, and ensure its loyalty to such standards as PDF/A.

An extensive list of security bulletins for almost all Adobe products and corresponding versions is released on their advisories page and security bulletins and in other corresponding venues. The detailed security update history for every version of Adobe Acrobat Reader has been made public in particular.

  • Acrobat Reader has contained support for JavaScript from the 3.02 version onwards.
  • The functionality permits a PDF document creator for including code that runs when the document has been read.
  • Mischievous PDF files that try to attack security vulnerabilities could be attacked to links over web pages or shared as email attachments.
  • On the other side, JavaScript is developed without a direct authorization to the filesystem for making it 'safe' and vulnerability has been reported for abuses like distributing mischievous code from Acrobat programs.

The applications of Adobe had already become the most famous targets of client software for attackers during the last 2009 quarter. McAfee anticipated that Adobe software, especially Flash and Reader would be the main aim for software attacks in 2010.

1. Warning in September 2006

David Kierznowski offered sample PDF files indicating JavaScript vulnerabilities on 2006 September 13. JavaScript can be shown with the embedded URLs and preferences menu that is intercepted by a dialog box of security warning to either block or allow the website from activating.

2. Warning in February 2009

Adobe published a Security Bulletin disclosing JavaScript vulnerabilities in Adobe Acrobat and Reader versions 9 and earlier in 2009 February 19. US-CERT suggested disabling JavaScript within the impacted products of Adobe, canceling the development with web browsers and Windows shell (while carrying out the developed release of de-integration of Internet Explorer), deactivating the indexing services of Adobe and avoiding every PDF file through external sources as a workaround for this problem.
