An integer overflow bug in the ziplist data structure used by all versions of Redis can be exploited to corrupt the heap and potentially result with remote code execution. The vulnerability involves modifying the default ziplist configuration parameters (hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries or zset-max-ziplist-value) to a very large value, and then constructing specially crafted commands to create very large ziplists. The problem is fixed in Redis versions 6.2.6, 6.0.16, 5.0.14. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from modifying the above configuration parameters. 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. Un bug de desbordamiento de enteros en la estructura de datos ziplist usada por todas las versiones de Redis puede ser explotado para corromper la pila y potencialmente resultar en una ejecuci\u00f3n de c\u00f3digo remota. La vulnerabilidad implica la modificaci\u00f3n de los par\u00e1metros de configuraci\u00f3n de ziplist por defecto (hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries o zset-max-ziplist-value) a un valor muy grande, y luego la construcci\u00f3n de comandos especialmente dise\u00f1ados para crear ziplists muy grandes. El problema es corregido en las versiones de Redis 6.2.6, 6.0.16 y 5.0.14. Una soluci\u00f3n adicional para mitigar el problema sin necesidad de parchear el ejecutable de redis-server es evitar que los usuarios modifiquen los par\u00e1metros de configuraci\u00f3n anteriores.
