"The version of Firefox installed on the remote macOS or Mac OS X host is prior to 92.0. It is, therefore, affected by
multiple vulnerabilities as referenced in the mfsa2021-38 advisory.

  - Firefox for Android allowed navigations through the `intent://` protocol, which could be used to cause
    crashes and UI spoofs. This bug only affects Firefox for Android. Other operating systems are
    unaffected. (CVE-2021-29993)

  - Mixed-content checks were unable to analyze opaque origins which led to some mixed content being loaded.
    (CVE-2021-38491)

  - When delegating navigations to the operating system, Firefox would accept the `mk` scheme which might
    allow attackers to launch pages and execute scripts in Internet Explorer in unprivileged mode. This
    bug only affects Firefox for Windows. Other operating systems are unaffected. (CVE-2021-38492)

  - Mozilla developers Gabriele Svelto and Tyson Smith reported memory safety bugs present in Firefox 91 and
    Firefox ESR 78.13. 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-2021-38493)

  - Mozilla developers Christian Holler and Lars T Hansen reported memory safety bugs present in Firefox 91.
    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-2021-38494)
