A vulnerability involving out-of-bounds read and integer overflow to buffer overflow exists starting with version 2.2 and prior to versions 5.0.13, 6.0.15, and 6.2.5. On 32-bit systems, Redis `*BIT*` command are vulnerable to integer overflow that can potentially be exploited to corrupt the heap, leak arbitrary heap contents or trigger remote code execution. The vulnerability involves changing the default `proto-max-bulk-len` configuration parameter to a very large value and constructing specially crafted commands bit commands. This problem only affects Redis on 32-bit platforms, or compiled as a 32-bit binary. Redis versions 5.0.`3m 6.0.15, and 6.2.5 contain patches for this issue. 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 que persiste en el disco. Se presenta una vulnerabilidad que implica una lectura fuera de l\u00edmites y el desbordamiento de enteros a desbordamiento de b\u00fafer a partir de la versi\u00f3n 2.2 y anterior a las versiones 5.0.13, 6.0.15 y 6.2.5. En los sistemas de 32 bits, el comando \"*BIT*\" de Redis es vulnerable al desbordamiento de enteros que puede ser potencialmente explotado para corromper la pila, filtrar contenidos arbitrarios de pila o desencadenar una ejecuci\u00f3n de c\u00f3digo remota . La vulnerabilidad implica cambiar el par\u00e1metro de configuraci\u00f3n \"proto-max-bulk-len\" predeterminado a un valor muy grande y construir comandos de bits especialmente dise\u00f1ados. Este problema s\u00f3lo afecta a Redis en plataformas de 32 bits, o compilado como un binario de 32 bits. Redis versiones 5.0.3m 6.0.15, y 6.2.5 contienen parches para este problema. Una soluci\u00f3n adicional para mitigar el problema sin parchear el ejecutable \"redis-server\" es prevenir que usuarios modifiquen el par\u00e1metro de configuraci\u00f3n \"proto-max-bulk-len\".
