Tenable has extracted the preceding description block directly from the Oracle Linux 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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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 < 118, Firefox ESR < 115.3, and     Thunderbird < 115.3. (CVE-2023-5176)

Note that Nessus relies on the presence of the package as reported by the vendor.

The remote MiracleLinux 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the AXSA:2023-6492:28 advisory.

    * firefox: use-after-free in workers (CVE-2023-3600)
      * Mozilla: Out-of-bounds write in PathOps (CVE-2023-5169)
      * Mozilla: Use-after-free in Ion Compiler (CVE-2023-5171)
      * Mozilla: Memory safety bugs fixed in Firefox 118, Firefox ESR 115.3, and Thunderbird 115.3     (CVE-2023-5176)
      * libvpx: Heap buffer overflow in vp8 encoding in libvpx (CVE-2023-5217)

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 macOS or Mac OS X host is prior to 118.0. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-41 advisory.

  - Memory safety bugs present in Firefox 117, Firefox ESR 115.2, and Thunderbird 115.2. 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-2023-5176)

  - A compromised content process could have provided malicious data to <code>FilterNodeD2D1</code> resulting     in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process. This bug     only affects Firefox on Windows. Other operating systems are unaffected. (CVE-2023-5168)

  - A compromised content process could have provided malicious data in a <code>PathRecording</code> resulting     in an out-of-bounds write, leading to a potentially exploitable crash in a privileged process.
    (CVE-2023-5169)

  - In canvas rendering, a compromised content process could have caused a surface to change unexpectedly,     leading to a memory leak of a privileged process. This memory leak could be used to effect a sandbox     escape if the correct data was leaked. (CVE-2023-5170)

  - During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing     an attacker to write two NUL bytes, and cause a potentially exploitable crash. (CVE-2023-5171)

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 Thunderbird installed on the remote Windows host is prior to 115.3. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-43 advisory.

    (CVE-2023-5169)

  - During Ion compilation, a Garbage Collection could have resulted in a use-after-free condition, allowing     an attacker to write two NUL bytes, and cause a potentially exploitable crash. (CVE-2023-5171)

  - If Windows failed to duplicate a handle during process creation, the sandbox code may have inadvertently     freed a pointer twice, resulting in a use-after-free and a potentially exploitable crash. This bug only     affects Firefox on Windows when run in non-standard configurations (such as using <code>runas</code>).
    Other operating systems are unaffected. (CVE-2023-5174)
