Security Alert (A18-11-05): Multiple Vulnerabilities in Adobe Flash Player and Adobe Reader/Acrobat


 

Published on: 14 November 2018

  
  

Description:

Security updates are released for Adobe Flash Player and Adobe Reader/Acrobat to address multiple vulnerabilities.  To exploit the vulnerabilities, a remote attacker would entice a targeted user to open a specially crafted PDF file, web page, Flash file, or document with embedded malicious Flash content.

Please note that Adobe announced that the support for Adobe Flash will be ceased at the end of 2020 and no security updates will be provided after that. The support for Adobe Acrobat XI 11.x and Adobe Reader XI 11.x ended on 15.10.2017. Users should arrange migrating to other supported technology.
