The remote CentOS Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2022:0514 advisory.

  - If a user installed an extension of a particular type, the extension could have auto-updated itself and     while doing so, bypass the prompt which grants the new version the new requested permissions. This     vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. (CVE-2022-22754)

  - If a user was convinced to drag and drop an image to their desktop or other folder, the resulting object     could have been changed into an executable script which would have run arbitrary code after the user     clicked on it. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6.
    (CVE-2022-22756)

  - If a document created a sandboxed iframe without <code>allow-scripts</code>, and subsequently appended an     element to the iframe's document that e.g. had a JavaScript event handler - the event handler would have     run despite the iframe's sandbox. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox     ESR < 91.6. (CVE-2022-22759)

  - When importing resources using Web Workers, error messages would distinguish the difference between     <code>application/javascript</code> responses and non-script responses. This could have been abused to     learn information cross-origin. This vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox     ESR < 91.6. (CVE-2022-22760)

  - Web-accessible extension pages (pages with a moz-extension:// scheme) were not correctly enforcing the     frame-ancestors directive when it was used in the Web Extension's Content Security Policy. This     vulnerability affects Firefox < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. (CVE-2022-22761)

  - When a worker is shutdown, it was possible to cause script to run late in the lifecycle, at a point after     where it should not be possible. This vulnerability affects Firefox < 96, Thunderbird < 91.6, and Firefox     ESR < 91.6. (CVE-2022-22763)

  - Mozilla developers Paul Adenot and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox     96 and Firefox ESR 91.5. 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 < 97, Thunderbird < 91.6, and Firefox ESR < 91.6. (CVE-2022-22764)

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