MuJS e892c9fdb contains an incorrect numeric conversion vulnerability in jsRisindex() in jsrun.c. A specially crafted JavaScript input containing an excessively large numeric array index can cause an out-of-range floating-point value to be converted to an integer without proper range validation. This results in undefined behavior and can cause process termination, leading to denial of service.

Mujs received multiple CVEs for security issues.
