"value": "Redis is an open source, in-memory database that persists on disk. In affected versions specially crafted Lua scripts executing in Redis can cause the heap-based Lua stack to be overflowed, due to incomplete checks for this condition. This can result with heap corruption and potentially remote code execution. This problem exists in all versions of Redis with Lua scripting support, starting from 2.6. The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. For users unable to update an additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to restrict EVAL and EVALSHA commands."

"value": "Redis es una base de datos en memoria de c\u00f3digo abierto que persiste en el disco. En las versiones afectadas, los scripts de Lua especialmente dise\u00f1ados que se ejecutan en Redis pueden causar el desbordamiento de la pila de Lua en la regi\u00f3n heap de la memoria, debido a las comprobaciones incompletas de esta condici\u00f3n. Esto puede resultar en una corrupci\u00f3n de la pila y potencialmente en una ejecuci\u00f3n de c\u00f3digo remota . Este problema se presenta en todas las versiones de Redis con soporte para scripts Lua, a partir de la 2.6. El problema es corregido en las versiones 6.2.6, 6.0.16 y 5.0.14. Para usuarios que no puedan actualizar una soluci\u00f3n adicional para mitigar el problema sin parchear el ejecutable del servidor Redis es evitar que los usuarios ejecuten scripts Lua. Esto puede hacerse usando ACL para restringir los comandos EVAL y EVALSHA"
