"The version of Foxit Reader for Mac installed on the remote macOS host is prior to 4.0. It is, therefore, affected by
a Signature Validation Bypass vulnerability that delivers incorrect validation results when validating certain PDF
files that have been modified maliciously or contains non-standard signatures.

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