"The version of Foxit Reader installed on the remote Windows host is
prior to 9.4. It is, therefore, affected by multiple vulnerabilities:

  - An out-of-bounds read/write vulnerability and crash
    when handling XFA element attributes. (CVE-2018-3956)

  - A signature validation bypass vulnerability which
    could lead to incorrect validation results.
    (CVE-2018-18688, CVE-2018-18689)

  - Flaws in how PDF files are processed/handled could
    lead to arbitrary code execution. An attacker can 
    exploit this by convincing a user to open a specially
    crafted file in order to cause the execution of arbitrary
    code. (CVE-2019-6728,CVE-2019-6729)

Additionally, the application was affected by multiple potential 
information disclosure, denial of service, and remote code execution
vulnerabilities.");
