The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2023:4954 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, Firefox ESR     < 115.2, and Thunderbird < 115.2. (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, Firefox ESR < 115.2, and Thunderbird < 115.2.
    (CVE-2023-4053)

  - When receiving rendering data over IPC `mStream` could have been destroyed when initialized, which could     have led to a use-after-free causing a potentially exploitable crash. This vulnerability affects Firefox <     117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2.
    (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. This     vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and     Thunderbird < 115.2. (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. This     vulnerability affects Firefox < 117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and     Thunderbird < 115.2. (CVE-2023-4575)

  - When `UpdateRegExpStatics` attempted to access `initialStringHeap` it could already have been garbage     collected prior to entering the function, which could potentially have led to an exploitable crash. This     vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2. (CVE-2023-4577)

  - When calling `JS::CheckRegExpSyntax` a Syntax Error could have been set which would end in calling     `convertToRuntimeErrorAndClear`. 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. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and Thunderbird < 115.2.
    (CVE-2023-4578)

  - Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing     the leak of sensitive information. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and     Thunderbird < 115.2. (CVE-2023-4580)

  - Excel `.xll` 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. This vulnerability affects Firefox <     117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2.
    (CVE-2023-4581)

  - When checking if the Browsing Context had been discarded in `HttpBaseChannel`, 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. This vulnerability affects Firefox < 117, Firefox ESR <     115.2, and Thunderbird < 115.2. (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. This vulnerability affects Firefox <     117, Firefox ESR < 102.15, Firefox ESR < 115.2, Thunderbird < 102.15, and Thunderbird < 115.2.
    (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. This vulnerability affects Firefox < 117, Firefox ESR < 115.2, and     Thunderbird < 115.2. (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.

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

  - 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)

  - 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-2023-4575)

  - 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)

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