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)

The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6320-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2023-4573, CVE-2023-4574,     CVE-2023-4575, CVE-2023-4578, CVE-2023-4581, CVE-2023-4583, CVE-2023-4584, CVE-2023-4585)

    Lukas Bernhard discovered that Firefox did not properly manage memory when the UpdateRegExpStatics     attempted to access initialStringHeap. An attacker could potentially exploit this issue to cause a     denial of service. (CVE-2023-4577)

    Malte Jrgens discovered that Firefox did not properly handle search queries if the search query itself     was a well formed URL. An attacker could potentially exploit this issue to perform spoofing attacks.
    (CVE-2023-4579)

    Harveer Singh discovered that Firefox did not properly handle push notifications stored on disk in private     browsing mode. An attacker could potentially exploits this issue to access sensitive information.
    (CVE-2023-4580)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.
