CVE-2021-29477

Redis es una estructura de datos en memoria de código abierto (con licencia BSD) almacenado, utilizado como base de datos, caché y agente de mensajes. Un bug de desbordamiento de enteros en Redis versión 6.0 o más reciente podría ser explotada usando el comando "STRALGO LCS" para corromper la pila y potencialmente resultar en una ejecución de código remota. El problema se corrigió en las versiones 6.2.3 y 6.0.13. Una solución alternativa para mitigar el problema sin parchear el ejecutable redis-server es usar la configuración de ACL para impedir que los clientes usen el comando "STRALGO LCS"

A flaw was found in redis. An integer overflow bug could be exploited to corrupt the heap and potentially result with remote code execution. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
