The remote AlmaLinux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the ALSA-2022:5482 advisory.

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 102.7.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2FIREFOX-2023-013 advisory.

  - Mozilla developers and community members Julian Hector, Randell Jesup, Gabriele Svelto, Tyson Smith,     Christian Holler, and Masayuki Nakano reported memory safety bugs present in Firefox 94. 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 < 95, Firefox ESR < 91.4.0, and     Thunderbird < 91.4.0. (CVE-2021-4129)

  - If an object prototype was corrupted by an attacker, they would have been able to set undesired attributes     on a JavaScript object, leading to privileged code execution. This vulnerability affects Firefox < 102,     Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-2200)

  - An out-of-bounds read can occur when decoding H264 video. This results in a potentially exploitable crash.
    This vulnerability affects Firefox ESR < 102.3, Thunderbird < 102.3, and Firefox < 105. (CVE-2022-3266)

  - An iframe that was not permitted to run scripts could do so if the user clicked on a     <code>javascript:</code> link. This vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird     < 102, and Thunderbird < 91.11. (CVE-2022-34468)

  - Session history navigations may have led to a use-after-free and potentially exploitable crash. This     vulnerability affects Firefox < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11.
    (CVE-2022-34470)

  - If there was a PAC URL set and the server that hosts the PAC was not reachable, OCSP requests would have     been blocked, resulting in incorrect error pages being shown. This vulnerability affects Firefox < 102,     Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34472)

  - A malicious website that could create a popup could have resized the popup to overlay the address bar with     its own content, resulting in potential user confusion or spoofing attacks. <br>*This bug only affects     Thunderbird for Linux. Other operating systems are unaffected.*. This vulnerability affects Firefox < 102,     Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34479)

  - In the <code>nsTArray_Impl::ReplaceElementsAt()</code> function, an integer overflow could have occurred     when the number of elements to replace was too large for the container. This vulnerability affects Firefox     < 102, Firefox ESR < 91.11, Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34481)

  - The Mozilla Fuzzing Team reported potential vulnerabilities present in Thunderbird 91.10. 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 < 102, Firefox ESR < 91.11,     Thunderbird < 102, and Thunderbird < 91.11. (CVE-2022-34484)

  - An out of date library (libusrsctp) contained vulnerabilities that could potentially be exploited. This     vulnerability affects Firefox < 108. (CVE-2022-46871)

  - 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)

  - By confusing the browser, the fullscreen notification could have been delayed or suppressed, resulting in     potential user confusion or spoofing attacks. This vulnerability affects Firefox < 108. (CVE-2022-46877)

  - 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)

  - An optimization in WebGL was incorrect in some cases, and could have led to memory corruption and a     potentially exploitable crash. *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 106. This     vulnerability affects Firefox < 106, Firefox ESR < 102.6, and Thunderbird < 102.6. (CVE-2022-46881)

  - 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)

  - Due to the Firefox GTK wrapper code's use of text/plain for drag data and GTK treating all text/plain     MIMEs containing file URLs as being dragged a website could arbitrarily read a file via a call to     <code>DataTransfer.setData</code>. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and     Firefox ESR < 102.7. (CVE-2023-23598)

  - When copying a network request from the developer tools panel as a curl command the output was not being     properly sanitized and could allow arbitrary commands to be hidden within. This vulnerability affects     Firefox < 109, Thunderbird < 102.7, and Firefox ESR < 102.7. (CVE-2023-23599)

  - Navigations were being allowed when dragging a URL from a cross-origin iframe into the same tab which     could lead to website spoofing attacks. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and     Firefox ESR < 102.7. (CVE-2023-23601)

  - A mishandled security check when creating a WebSocket in a WebWorker caused the Content Security Policy     connect-src header to be ignored. This could lead to connections to restricted origins from inside     WebWorkers. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and Firefox ESR < 102.7.
    (CVE-2023-23602)

  - Regular expressions used to filter out forbidden properties and values from style directives in calls to     <code>console.log</code> weren't accounting for external URLs. Data could then be potentially exfiltrated     from the browser. This vulnerability affects Firefox < 109, Thunderbird < 102.7, and Firefox ESR < 102.7.
    (CVE-2023-23603)

  - Mozilla developers and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox 108 and     Firefox ESR 102.6. 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 <     109, Thunderbird < 102.7, and Firefox ESR < 102.7. (CVE-2023-23605)

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