"The remote AlmaLinux 8 host has a package installed that is affected by multiple vulnerabilities as referenced in the
ALSA-2023:4952 advisory.

  - 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. This vulnerability affects Firefox < 116.
    (CVE-2023-4051)

  - 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. This vulnerability affects Firefox < 116. (CVE-2023-4053)

  - 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)

  - 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)

  - 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)

  - 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
