"According to its version, the Foxit PDF SDK ActiveX application
installed on the remote Windows host is prior to 5.5.1. It is, 
therefore, affected by multiple vulnerabilities:

  - A remote code execution vulnerability exists due to 
    a lack of security permission control which could allow
    LaunchURL actions and links to execute programs without
    a user's consent. An unauthenticated, remote 
    attacker can exploit this by convincing a user to open a
    specially crafted file, to execute arbitrary code.
    (CVE-2018-19418, CVE-2018-19445, CVE-2018-19450, CVE-2018-19451)

  - A remote code execution vulnerability exists due to 
    a lack of security permission control which could allow
    javascript and exportasFDF to write arbitrary files without
    a user's consent. An unauthenticated, remote 
    attacker can exploit this by convincing a user to open a
    specially crafted file, to execute arbitrary code.
    (CVE-2018-19446, CVE-2018-19449)

  - A remote code execution vulnerability exists due to 
    a stack buffer overflow in string1 URI parsing. 
    An unauthenticated, remote attacker can exploit this by 
    convincing a user to open a specially crafted file, to 
    execute arbitrary code. (CVE-2018-19447)

  - A remote code execution vulnerability exists due to 
    a use-after-free occurring when a javascript command
    is triggered by a mouse enter action or focus loss. 
    An unauthenticated, remote attacker can exploit this by 
    convincing a user to open a specially crafted file, to 
    execute arbitrary code. (CVE-2018-19452, CVE-2018-19444)

  - A remote code execution vulnerability exists due to 
    an uninitialized object reference as a result of a timer
    not ending when a form loses focus. An unauthenticated, 
    remote attacker can exploit this by convincing a user to 
    open a specially crafted file, to execute arbitrary code.
