"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:9067 advisory.

  - A use-after-free in WebGL extensions could have led to a potentially exploitable crash. This vulnerability
    affects Firefox < 107, Firefox ESR < 102.6, and Thunderbird < 102.6. (CVE-2022-46882)

  - An attacker who compromised a content process could have partially escaped the sandbox to read arbitrary
    files via clipboard-related IPC messages.<br>*This bug only affects Thunderbird for Linux. Other operating
    systems are unaffected.*. This vulnerability affects Firefox < 108, Firefox ESR < 102.6, and Thunderbird <
    102.6. (CVE-2022-46872)

  - 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.<br/>*Note*: This issue was originally included in the advisories for Thunderbird 102.6,
    but a patch (specific to Thunderbird) was omitted, resulting in it actually being fixed in Thunderbird
    102.6.1. This vulnerability affects Firefox < 108, Thunderbird < 102.6.1, Thunderbird < 102.6, and Firefox
    ESR < 102.6. (CVE-2022-46874)

  - Mozilla developers Randell Jesup, Valentin Gosu, Olli Pettay, and the Mozilla Fuzzing Team reported memory
    safety bugs present in Thunderbird 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. This
    vulnerability affects Firefox < 108, Firefox ESR < 102.6, and Thunderbird < 102.6. (CVE-2022-46878)

  - A missing check related to tex units could have led to a use-after-free and potentially exploitable
    crash.<br />*Note*: This advisory was added on December 13th, 2022 after we better understood the impact
    of the issue. The fix was included in the original release of Firefox 105. This vulnerability affects
    Firefox ESR < 102.6, Firefox < 105, and Thunderbird < 102.6. (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.");
