The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 137.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2025-23 advisory.

  - Memory safety bugs present in Firefox 136 and Thunderbird 136. Some of these bugs showed evidence of     memory corruption and we presume that with enough effort some of these could have been exploited to run     arbitrary code. (CVE-2025-3034)

  - JavaScript code running while transforming a document with the XSLTProcessor could lead to a use-after-     free. (CVE-2025-3028)

  - An attacker could read 32 bits of values spilled onto the stack in a JIT compiled function.
    (CVE-2025-3031)

  - Leaking of file descriptors from the fork server to web content processes could allow for privilege     escalation attacks. (CVE-2025-3032)

  - A crafted URL containing specific Unicode characters could have hidden the true origin of the page,     resulting in a potential spoofing attack. (CVE-2025-3029)
