Description Christopher Fore 2024-04-21 17:54:08 UTC

The following only effect rapid (125.0):

CVE-2024-3853:

A use-after-free could result if a JavaScript realm was in the process of being initialized when a garbage collection started.


CVE-2024-3855:

In certain cases the JIT incorrectly optimized MSubstr operations, which led to out-of-bounds reads.


CVE-2024-3856:

A use-after-free could occur during WASM execution if garbage collection ran during the creation of an array.


CVE-2024-3858:

It was possible to mutate a JavaScript object so that the JIT could crash while tracing it.


CVE-2024-3860:

An out-of-memory condition during object initialization could result in an empty shape list. If the JIT subsequently traced the object it would crash.


CVE-2024-3862:

The MarkStack assignment operator, part of the JavaScript engine, could access uninitialized memory if it were used in a self-assignment.


CVE-2024-3865:

Memory safety bugs present in Firefox 124. 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.
