CVE-2023-4053: The Mozilla Foundation Security Advisory describes this flaw as: 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.
CVE-2023-4573: The Mozilla Foundation Security Advisory describes this flaw as: 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.
CVE-2023-4574: The Mozilla Foundation Security Advisory describes this flaw as: 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: The Mozilla Foundation Security Advisory describes this flaw as: 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-2023-4577: The Mozilla Foundation Security Advisory describes this flaw as: 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.
CVE-2023-4578: The Mozilla Foundation Security Advisory describes this flaw as: When calling JS::CheckRegExpSyntax a Syntax Error could have been set which would end in calling convertToRuntimeErrorAndClear.

CVE-2023-4583: The Mozilla Foundation Security Advisory describes this flaw as: 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.
CVE-2023-4584: The Mozilla Foundation Security Advisory describes this flaw as: 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.
