Descriptions
A heap overflow issue was found in Redis in versions before 5.0.10, before 6.0.9 and before 6.2.0 when using a heap allocator other than jemalloc or glibc's malloc, leading to potential out of bound write or process crash. Effectively this flaw does not affect the vast majority of users, who use jemalloc or glibc malloc.
Se encontró un problema de desbordamiento de pila en Redis en las versiones anteriores a 5.0.10, versiones anteriores a 6.0.9 y versiones anteriores a 6.2.0, cuando se usaba un asignador de pila que no fuera jemalloc o malloc de glibc, conllevando a un posible bloqueo del proceso o de escritura fuera de límites. Efectivamente, este fallo no afecta a la gran mayoría de usuarios que usan jemalloc o glibc malloc.
