An attacker was able to perform an out-of-bounds read or write on a JavaScript object by fooling range-based bounds check elimination. This vulnerability affects Firefox < 124.0.1.
Un atacante pudo realizar una lectura o escritura fuera de los límites en un objeto JavaScript engañando la eliminación de verificación de los límites basada en rangos. Esta vulnerabilidad afecta a Firefox < 124.0.1.
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the SpiderMonkey JIT compiler. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process at low integrity.
