"The version of Thunderbird installed on the remote macOS or Mac OS X host is prior to 150.0.1. It is, therefore,
affected by multiple vulnerabilities as referenced in the mfsa2026-38 advisory.

  - Information disclosure due to incorrect boundary conditions in the Audio/Video component. This
    vulnerability was fixed in Firefox 150.0.1, Firefox ESR 140.10.1, Firefox ESR 115.35.1, Thunderbird
    150.0.1, and Thunderbird 140.10.1. (CVE-2026-7320)

  - Memory safety bugs present in Thunderbird ESR 140.10.0 and Thunderbird 150.0.0. 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-2026-7322, CVE-2026-7323)
