The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2022:4872 advisory.

  - Mozilla developers Andrew McCreight, Nicolas B. Pierron, and the Mozilla Fuzzing Team reported memory     safety bugs present in Firefox 100 and Firefox ESR 91.9. 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 Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10.
    (CVE-2022-31747)

  - A malicious website could have learned the size of a cross-origin resource that supported Range requests.
    This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31736)

  - A malicious webpage could have caused an out-of-bounds write in WebGL, leading to memory corruption and a     potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox < 101, and Firefox     ESR < 91.10. (CVE-2022-31737)

  - When exiting fullscreen mode, an iframe could have confused the browser about the current state of     fullscreen, resulting in potential user confusion or spoofing attacks. This vulnerability affects     Thunderbird < 91.10, Firefox < 101, and Firefox ESR < 91.10. (CVE-2022-31738)

  - On arm64, WASM code could have resulted in incorrect assembly generation leading to a register allocation     problem, and a potentially exploitable crash. This vulnerability affects Thunderbird < 91.10, Firefox <     101, and Firefox ESR < 91.10. (CVE-2022-31740)

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

The version of firefox installed on the remote host is prior to 91.10.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2023-011 advisory.

    2024-04-25: CVE-2022-29913 was added to this advisory.

    The parent process would not properly check whether the Speech Synthesis feature is enabled, when     receiving instructions from a child process. This vulnerability affects Thunderbird < 91.9.
    (CVE-2022-29913)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue as a malicious     website that could have learned the size of a cross-origin resource that supported Range requests.

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue as a malicious     webpage that could have caused an out-of-bounds write in WebGL, leading to memory corruption and a     potentially exploitable crash. (CVE-2022-31737)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of when exiting     fullscreen mode, an iframe could have confused the browser about the current state of the fullscreen,     resulting in potential user confusion or spoofing attacks. (CVE-2022-31738)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue on arm64; WASM     code could have resulted in incorrect assembly generation, leading to a register allocation problem and a     potentially exploitable crash. (CVE-2022-31740)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue as having a     crafted CMS message that could have been processed incorrectly, leading to an invalid memory read and     potential memory corruption. (CVE-2022-31741)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue as an attacker     could have exploited a timing attack by sending a large number of allowCredential entries and detecting     the difference between invalid key handles and cross-origin key handles. This could have led to cross-     origin account linking in violation of WebAuthn goals. (CVE-2022-31742)

    A flaw was found in Mozilla. The Mozilla Foundation Security Advisory describes the issue of Mozilla     developers and community members reporting memory safety bugs present in Firefox 100 and Firefox ESR 91.0.
    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-2022-31747)
