CVE-2021-3470  (opens in a new tab)
CWE-787  (opens in a new tab)

How to fix?

Upgrade antirez/redis to version 5.0.10, 6.0.9 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-bounds Write. 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.
