    (and earlier) are affected by an information exposure vulnerability, that could enable an attacker to get
    a DNS interaction and track if the user has opened or closed a PDF file when loaded from the filesystem
    without a prompt. User interaction is required to exploit this vulnerability. (CVE-2020-29075)

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