"The version of Firefox installed on the remote Windows host is prior to 117.0. It is, therefore, affected by multiple
vulnerabilities as referenced in the mfsa2023-34 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)

  - 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)

  - Search queries in the default search engine could appear to have been the currently navigated URL if the
    search query itself was a well formed URL. This could have led to a site spoofing another if it had been
    maliciously set as the default search engine. (CVE-2023-4579)

  - 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)
