"The remote AlmaLinux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the
ALSA-2022:1705 advisory.

  - Mozilla developers Andrew McCreight, Gabriele Svelto, Tom Ritter and the Mozilla Fuzzing Team reported
    memory safety bugs present in Firefox 99 and Firefox ESR 91.8. 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. This vulnerability affects Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100.
    (CVE-2022-29917)

  - Documents in deeply-nested cross-origin browsing contexts could have obtained permissions granted to the
    top-level origin, bypassing the existing prompt and wrongfully inheriting the top-level permissions. This
    vulnerability affects Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100. (CVE-2022-29909)

  - An improper implementation of the new iframe sandbox keyword <code>allow-top-navigation-by-user-
    activation</code> could lead to script execution without <code>allow-scripts</code> being present. This
    vulnerability affects Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100. (CVE-2022-29911)

  - Requests initiated through reader mode did not properly omit cookies with a SameSite attribute. This
    vulnerability affects Thunderbird < 91.9, Firefox ESR < 91.9, and Firefox < 100. (CVE-2022-29912)

  - When reusing existing popups Firefox would have allowed them to cover the fullscreen notification UI,
    which could have enabled browser spoofing attacks. This vulnerability affects Thunderbird < 91.9, Firefox
    ESR < 91.9, and Firefox < 100. (CVE-2022-29914)

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