Descriptions

An integer overflow in the getnum function in lua_struct.c in Redis before 6.0.3 allows context-dependent attackers with permission to run Lua code in a Redis session to cause a denial of service (memory corruption and application crash) or possibly bypass intended sandbox restrictions via a large number, which triggers a stack-based buffer overflow. NOTE: this issue exists because of a CVE-2015-8080 regression.

Un desbordamiento de enteros en la función getnum en el archivo lua_struct.c en Redis versiones anteriores a 6.0.3, permite a atacantes dependiendo del contexto, con permiso para ejecutar el código Lua en una sesión de Redis, causar una denegación de servicio (corrupción de la memoria y bloqueo de la aplicación) o posiblemente omitir las restricciones del sandbox previstas por medio de un número grande, lo que desencadena un desbordamiento de búfer en la región stack de la pila. NOTA: este problema se presenta debido a una regresión de CVE-2015-8080
