"The version of firefox installed on the remote host is prior to 102.10.0-1. It is, therefore, affected by multiple
vulnerabilities as referenced in the ALAS2FIREFOX-2023-006 advisory.

  - Unexpected data returned from the Safe Browsing API could have led to memory corruption and a potentially
    exploitable crash. This vulnerability affects Thunderbird < 102.10 and Firefox ESR < 102.10.
    (CVE-2023-1945)

  - A website could have obscured the fullscreen notification by using a combination of
    <code>window.open</code>, fullscreen requests, <code>window.name</code> assignments, and
    <code>setInterval</code> calls. This could have led to user confusion and possible spoofing attacks. This
    vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android <
    112, and Thunderbird < 102.10. (CVE-2023-29533)

  - Following a Garbage Collector compaction, weak maps may have been accessed before they were correctly
    traced. This resulted in memory corruption and a potentially exploitable crash. This vulnerability affects
    Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird <
    102.10. (CVE-2023-29535)

  - An attacker could cause the memory manager to incorrectly free a pointer that addresses attacker-
    controlled memory, resulting in an assertion, memory corruption, or a potentially exploitable crash. This
    vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android <
    112, and Thunderbird < 102.10. (CVE-2023-29536)

  - When handling the filename directive in the Content-Disposition header, the filename would be truncated if
    the filename contained a NULL character. This could have led to reflected file download attacks
    potentially tricking users to install malware. This vulnerability affects Firefox < 112, Focus for Android
    < 112, Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird < 102.10. (CVE-2023-29539)

  - Firefox did not properly handle downloads of files ending in <code>.desktop</code>, which can be
    interpreted to run attacker-controlled commands. <br>*This bug only affects Firefox for Linux on certain
    Distributions. Other operating systems are unaffected, and Mozilla is unable to enumerate all affected
    Linux Distributions.*. This vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR <
    102.10, Firefox for Android < 112, and Thunderbird < 102.10. (CVE-2023-29541)

  - A wrong lowering instruction in the ARM64 Ion compiler resulted in a wrong optimization result. This
    vulnerability affects Firefox < 112, Focus for Android < 112, Firefox ESR < 102.10, Firefox for Android <
    112, and Thunderbird < 102.10. (CVE-2023-29548)

  - Mozilla developers Randell Jesup, Andrew Osmond, Sebastian Hengst, Andrew McCreight, and the Mozilla
    Fuzzing Team reported memory safety bugs present in Firefox 111 and Firefox ESR 102.9. 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 Firefox < 112, Focus for Android < 112,
    Firefox ESR < 102.10, Firefox for Android < 112, and Thunderbird < 102.10. (CVE-2023-29550)

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