"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 138.0.1. It is, therefore,
affected by multiple vulnerabilities as referenced in the mfsa2025-35 advisory.

  - It was possible to craft an email that showed a tracking link as an attachment. If the user attempted to
    open the attachment, Thunderbird automatically accessed the link. The configuration to block remote
    content did not prevent that. Thunderbird has been fixed to no longer allow access to web pages listed in
    the X-Mozilla-External-Attachment-URL header of an email. (CVE-2025-3932)

  - Thunderbird parses addresses in a way that can allow sender spoofing in case the server allows an invalid
    From address to be used. For example, if the From header contains an (invalid) value Spoofed Name
    <[email protected]> <[email protected]>, Thunderbird treats [email protected] as the actual
    address. (CVE-2025-3875)

  - Thunderbird's handling of the X-Mozilla-External-Attachment-URL header can be exploited to execute
    JavaScript in the file:/// context. By crafting a nested email attachment (message/rfc822) and setting its
    content type to application/pdf, Thunderbird may incorrectly render it as HTML when opened, allowing the
    embedded JavaScript to run without requiring a file download. This behavior relies on Thunderbird auto-
    saving the attachment to /tmp and linking to it via the file:/// protocol, potentially enabling JavaScript
    execution as part of the HTML. (CVE-2025-3909)

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