The remote Oracle Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2023-5019 advisory.
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)
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 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)
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)
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)
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)
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)
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)
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)
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)
Push notifications stored on disk in private browsing mode were not being encrypted potentially allowing the leak of sensitive information. (CVE-2023-4580)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
