"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 140.16. It is, therefore, affected
by multiple vulnerabilities as referenced in the mfsa2026-95 advisory.

  - Privilege escalation due to incorrect boundary conditions in the Graphics: WebRender component. This
    vulnerability was fixed in Firefox 156, Firefox ESR 115.41, Firefox ESR 140.16, Firefox ESR 153.3,
    Thunderbird 156, and Thunderbird 140.16. (CVE-2026-92020)

  - A maliciously constructed mail header could lead to multiple fields being parsed as one, or potential
    memory safety violations. (CVE-2026-92238)

  - A maliciously constructed IMAP line could cause an out-of-bounds buffer read. (CVE-2026-92239)

  - A malicious or compromised IMAP server can trigger an out-of-bounds read in the IMAP response parser by
    sending an untagged ' ID' response, crashing Thunderbird. The affected parsing path is reachable before
    authentication. (CVE-2026-92240)

  - Use-after-free in the Audio/Video: Web Codecs component. This vulnerability was fixed in Firefox 156,
    Firefox ESR 140.16, Firefox ESR 153.3, Thunderbird 156, and Thunderbird 140.16. (CVE-2026-92005)

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