The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 102.6.1. It is, therefore, affected by a vulnerability as referenced in the mfsa2022-54 advisory.

  • A file with a long filename could have had its filename truncated to remove the valid extension, leaving a malicious extension in its place. This could potentially led to user confusion and the execution of malicious code.<br />Note: This issue was originally included in the advisories for Thunderbird 102.6, but a patch (specific to Thunderbird) was omitted, resulting in it actually being fixed in Thunderbird 102.6.1 (CVE-2022-46874)

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