"According to its version, the Foxit PhantomPDF application (formally
known as Phantom) installed on the remote Windows host is prior to
8.3.9. It is, therefore, affected by following vulnerabilities:

  - An out-of-bounds read/write vulnerability exists
    when handling certain XFA element attributes.
    This occurs due to improper calculation of a
    null-terminated character and may cause an application crash.
    (CVE-2018-3956)

  - A signature validation bypass vulnerability exists
    which provides incorrect results when validating
    certain PDF documents.
    (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.");
