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.

    The Mozilla Foundation describes this issue as follows:Unexpected data returned from the Safe Browsing API     could have led to memory corruption and a potentially exploitable crash. (CVE-2023-1945)

    The Mozilla Foundation describes this issue as follows:A website could have obscured the fullscreen     notification by using a combination of window.open, fullscreen requests, window.name assignments, and     setInterval calls. This could have led to user confusion and possible spoofing attacks. (CVE-2023-29533)

    The Mozilla Foundation describes this issue as follows: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. (CVE-2023-29535)

    The Mozilla Foundation describes this issue as follows: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. (CVE-2023-29536)

    The Mozilla Foundation describes this issue as follows: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.
    (CVE-2023-29539)

    The Mozilla Foundation describes this issue as follows:Firefox did not properly handle downloads of files     ending in .desktop, which can be interpreted to run attacker-controlled commands.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. (CVE-2023-29541)

    The Mozilla Foundation describes this issue as follows:A wrong lowering instruction in the ARM64 Ion     compiler resulted in a wrong optimization result. (CVE-2023-29548)

    The Mozilla Foundation describes this issue as follows:Mozilla developers Andrew Osmond, Sebastian Hengst,     Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Thunderbird 102.9,     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. (CVE-2023-29550)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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

The remote CentOS Linux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the CESA-2023:1787 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)

  - There exists a use after free/double free in libwebp. An attacker can use the ApplyFiltersAndEncode()     function and loop through to free best.bw and assign best = trial pointer. The second loop will then     return 0 because of an Out of memory error in VP8 encoder, the pointer is still assigned to trial and the     AddressSanitizer will attempt a double free. (CVE-2023-1999)

  - 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.

  - 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)
