Description TEJ RATHI 2026-09-29 10:40:25 UTC
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

MuJS e892c9fdb contains an incorrect numeric conversion vulnerability in jsR_isindex() 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.
