"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:1705 advisory.

  - 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)

  - Firefox behaved slightly differently for already known resources when loading CSS resources involving CSS
    variables. This could have been used to probe the browser history. This vulnerability affects Thunderbird
    < 91.9, Firefox ESR < 91.9, and Firefox < 100. (CVE-2022-29916)

  - 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)
