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.

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.
