Sometimes, when invalidating JIT code while following an iterator, the newly generated code could be overwritten incorrectly. This could lead to a potentially exploitable crash (CVE-2023-25751). When accessing throttled streams, the count of available bytes needed to be checked in the calling function to be within bounds. This may have lead future code to be incorrect and vulnerable (CVE-2023-25752). While implementing on AudioWorklets, some code may have casted one type to another, invalid, dynamic type. This could have lead to a potentially exploitable crash (CVE-2023-28162). Dragging a URL from a cross-origin iframe that was removed during the drag could have lead to user confusion and website spoofing attacks (CVE-2023-28164). Mozilla developers Timothy Nikkel, Andrew McCreight, and the Mozilla Fuzzing Team reported memory safety bugs present in Firefox ESR 102.8. 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-2023-28176).
