The version of Adobe Reader installed on the remote Windows host is a version prior or equal to 2017.011.30194, 2020.001.30020, or 2021.001.20150. It is, therefore, affected by multiple vulnerabilities, including the following:

  - Out-of-bounds write vulnerabilities that can result in arbitrary code execution. (CVE-2021-21044,     CVE-2021-21038, CVE-2021-21086)

  - Use after free vulnerabilities that can result in arbitrary code execution. (CVE-2021-28562,     CVE-2021-28550, CVE-2021-28553)

  - An out-of-bounds read vulnerability that can result in a memory leak. (CVE-2021-28557)


Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
