An integer overflow bug in the underlying string library can be used to corrupt the heap and potentially result with denial of service or remote code execution. The vulnerability involves changing the default proto-max-bulk-len configuration parameter to a very large value and constructing specially crafted network payloads or commands. The problem is fixed in Redis versions 6.2.6, 6.0.16 and 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the proto-max-bulk-len configuration parameter. This can be done using ACL to restrict unprivileged users from using the CONFIG SET command."}, {"lang": "es", "value": "Redis es una base de datos en memoria de c\u00f3digo abierto que persiste en el disco.

La vulnerabilidad implica cambiar el par\u00e1metro de configuraci\u00f3n proto-max-bulk-len predeterminado a un valor muy grande y construir cargas \u00fatiles o comandos de red especialmente dise\u00f1ados.

Una soluci\u00f3n adicional para mitigar el problema sin necesidad de parchear el ejecutable de redis-server es prevenir que los usuarios modifiquen el par\u00e1metro de configuraci\u00f3n proto-max-bulk-len.
