source, in-memory database that persists on disk. In affected versions an integer overflow bug in Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves changing the default proto-max-bulk-len and client-query-buffer-limit configuration parameters to very large values and constructing specially crafted very large stream elements. The problem is fixed in Redis 6.2.6, 6.0.16 and 5.0.14. For users unable to upgrade 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. En las versiones afectadas, un bug de desbordamiento de enteros en Redis puede ser explotado para corromper la pila y resultar potencialmente en una ejecuci\u00f3n de c\u00f3digo remota . La vulnerabilidad consiste en cambiar los par\u00e1metros de configuraci\u00f3n predeterminados proto-max-bulk-len y client-query-buffer-limit a valores muy grandes y construir elementos de flujo muy grandes especialmente dise\u00f1ados. El problema es corregido en Redis 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 de redis-server es evitar que los usuarios modifiquen el par\u00e1metro de configuraci\u00f3n proto-max-bulk-len.
