Upgrade wasmtime-internal-cranelift to version 38.0.3 or higher.
Overview
wasmtime-internal-cranelift is an Integration between Cranelift and Wasmtime
Affected versions of this package are vulnerable to Improper Handling of Exceptional Conditions via the implementation of component-model related host-to-wasm trampolines. An attacker can cause the host to crash with a segmentation fault or assertion failure by crafting a component and invoking it in a specific manner that abuses the setjmp and longjmp functions in C.
Note: Only embeddings that use or invoke functions with specific component type signatures may be affected.
