Security updates are released for 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.
Please also note that the support for Adobe Acrobat XI 11.x and Adobe Reader XI 11.x ended on 15.10.2017. Users should arrange software replacement by adopting other supported products as soon as possible.
A successful exploitation could lead to arbitrary code execution, information disclose or security bypass on an affected system.
