"The remote Oracle Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the
ELSA-2022-90671 advisory.

  - An optimization in WebGL was incorrect in some cases, and could have led to memory corruption and a
    potentially exploitable crash.  (CVE-2022-46881)

  - A use-after-free in WebGL extensions could have led to a potentially exploitable crash.  (CVE-2022-46882)

  - A file with a long filename could have had its filename truncated to remove the valid extension, leaving a
    malicious extension in its place. This could potentially led to user confusion and the execution of
    malicious code.  (CVE-2022-46874)

  - Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory
    safety bugs present in Firefox 107 and Firefox ESR 102.5. 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-2022-46878)

  - An attacker who compromised a content process could have partially escaped the sandbox to read arbitrary
    files via clipboard-related IPC messages. This bug only affects Thunderbird for Linux. Other operating
    systems are unaffected.  (CVE-2022-46872)

  - A missing check related to tex units could have led to a use-after-free and potentially exploitable crash.
    (CVE-2022-46880)

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