Descriptions

Redis is an in-memory database that persists on disk. Authenticated users issuing specially crafted `SETRANGE` and `SORT(_RO)` commands can trigger an integer overflow, resulting with Redis attempting to allocate impossible amounts of memory and abort with an out-of-memory (OOM) panic. The problem is fixed in Redis versions 7.0.8, 6.2.9 and 6.0.17. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Redis es una base de datos en memoria que persiste en el disco. Los usuarios autenticados que emiten comandos `SETRANGE` y `SORT(_RO)` especialmente manipulados pueden desencadenar un desbordamiento de enteros, lo que hace que Redis intente asignar cantidades imposibles de memoria y aborte con un pánico de falta de memoria (OOM). El problema se solucionó en las versiones 7.0.8, 6.2.9 y 6.0.17 de Redis. Se recomienda a los usuarios que actualicen. No se conocen soluciones para esta vulnerabilidad.
