"The version of Firefox 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 mfsa2026-35 advisory.

  - Memory safety bugs present in Firefox ESR 140.10.0 and Firefox 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-2026-7323)

  - 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, and Firefox ESR 115.35.1.

  - Memory safety bugs present in Firefox ESR 115.35.0, Firefox ESR 140.10.0 and Firefox 150.0.0. Some of
