"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:5469 advisory.

  - The Mozilla Fuzzing Team reported potential vulnerabilities present in Thunderbird 91.10. 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 Firefox < 102, Firefox ESR < 91.11,
    Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34484)

  - If an object prototype was corrupted by an attacker, they would have been able to set undesired attributes
    on a JavaScript object, leading to privileged code execution. This vulnerability affects Firefox < 102,
    Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-2200)

  - An attacker could have injected CSS into stylesheets accessible via internal URIs, such as resource:, and
    in doing so bypass a page's Content Security Policy. This vulnerability affects Firefox ESR < 91.11,
    Thunderbird < 102, Thunderbird < 91.11, and Firefox < 101. (CVE-2022-31744)

  - An iframe that was not permitted to run scripts could do so if the user clicked on a
    <code>javascript:</code> link. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird
    < 102, and Thunderbird < 91.11. (CVE-2022-34468)

  - Session history navigations may have led to a use-after-free and potentially exploitable crash. This
    vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.
    (CVE-2022-34470)
