The version of Firefox ESR installed on the remote macOS or Mac OS X host is prior to 115.2. It is, therefore, affected by multiple vulnerabilities as referenced in the mfsa2023-36 advisory.

  - When receiving rendering data over IPC <code>mStream</code> could have been destroyed when initialized,     which could have led to a use-after-free causing a potentially exploitable crash. (CVE-2023-4573)

  - When creating a callback over IPC for showing the Color Picker window, multiple of the same callbacks     could have been created at a time and eventually all simultaneously destroyed as soon as one of the     callbacks finished. This could have led to a use-after-free causing a potentially exploitable crash.
    (CVE-2023-4574)

  - When creating a callback over IPC for showing the File Picker window, multiple of the same callbacks could     have been created at a time and eventually all simultaneously destroyed as soon as one of the callbacks     finished. This could have led to a use-after-free causing a potentially exploitable crash. (CVE-2023-4575)

  - On Windows, an integer overflow could occur in <code>RecordedSourceSurfaceCreation</code> which resulted     in a heap buffer overflow potentially leaking sensitive data that could have led to a sandbox escape. This     bug only affects Firefox on Windows. Other operating systems are unaffected. (CVE-2023-4576)

  - When <code>UpdateRegExpStatics</code> attempted to access <code>initialStringHeap</code> it could already     have been garbage collected prior to entering the function, which could potentially have led to an     exploitable crash. (CVE-2023-4577)

  - A website could have obscured the full screen notification by using the file open dialog. This could have     led to user confusion and possible spoofing attacks. (CVE-2023-4051)

  - When calling <code>JS::CheckRegExpSyntax</code> a Syntax Error could have been set which would end in     calling <code>convertToRuntimeErrorAndClear</code>. A path in the function could attempt to allocate     memory when none is available which would have caused a newly created Out of Memory exception to be     mishandled as a Syntax Error. (CVE-2023-4578)

  - A website could have obscured the full screen notification by using a URL with a scheme handled by an     external program, such as a mailto URL. This could have led to user confusion and possible spoofing     attacks. (CVE-2023-4053)

  - Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing     the leak of sensitive information. (CVE-2023-4580)

  - Excel <code>.xll</code> add-in files did not have a blocklist entry in Firefox's executable blocklist     which allowed them to be downloaded without any warning of their potential harm. (CVE-2023-4581)

  - Due to large allocation checks in Angle for glsl shaders being too lenient a buffer overflow could have     occured when allocating too much private shader memory on mac OS.  This bug only affects Firefox on macOS.
    Other operating systems are unaffected. (CVE-2023-4582)

  - When checking if the Browsing Context had been discarded in <code>HttpBaseChannel</code>, if the load     group was not available then it was assumed to have already been discarded which was not always the case     for private channels after the private session had ended. (CVE-2023-4583)

  - Memory safety bugs present in Firefox 116, Firefox ESR 102.14, Firefox ESR 115.1, Thunderbird 102.14, and     Thunderbird 115.1. 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-2023-4584)

  - Memory safety bugs present in Firefox 116, Firefox ESR 115.1, and Thunderbird 115.1. 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-2023-4585)

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