How to fix?

There is no fixed version for RHEL:7 redis.

NVD Description

Note: Versions mentioned in the description apply only to the upstream redis package and not the redis package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
