"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:7070 advisory.

  - A same-origin policy violation could have allowed the theft of cross-origin URL entries, leaking the
    result of a redirect, via `performance.getEntries()`. This vulnerability affects Firefox < 106, Firefox
    ESR < 102.4, and Thunderbird < 102.4. (CVE-2022-42927)

  - Certain types of allocations were missing annotations that, if the Garbage Collector was in a specific
    state, could have lead to memory corruption and a potentially exploitable crash. This vulnerability
    affects Firefox < 106, Firefox ESR < 102.4, and Thunderbird < 102.4. (CVE-2022-42928)

  - If a website called `window.print()` in a particular way, it could cause a denial of service of the
    browser, which may persist beyond browser restart depending on the user's session restore settings. This
    vulnerability affects Firefox < 106, Firefox ESR < 102.4, and Thunderbird < 102.4. (CVE-2022-42929)

  - Mozilla developers Ashley Hale and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox
    105 and Firefox ESR 102.3. 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 < 106, Firefox ESR < 102.4, and Thunderbird < 102.4. (CVE-2022-42932)

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