Foxit Reader < 4.0 Privilege Escalation (macOS)

Medium Nessus Plugin ID 139329


The remote macOS host is affected by a privilege escalation vulnerability.


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.


Upgrade to Foxit Reader version 4.0 or later.
