Summary

Memory access due to code generation flaw in Cranelift module

Details

There is a bug in 0.73.0 of the Cranelift x64 backend that can create a scenario that could result in a potential sandbox escape in a WebAssembly module. Users of versions 0.73.0 of Cranelift should upgrade to either 0.73.1 or 0.74 to remediate this vulnerability. Users of Cranelift prior to 0.73.0 should update to 0.73.1 or 0.74 if they were not using the old default backend.
