## Description

A stack-buffer overflow vulnerability was found in the Redis hyperloglog
data structure versions 3.x before 3.2.13, 4.x before 4.0.14 and 5.x before
5.0.4. By corrupting a hyperloglog using the SETRANGE command, an attacker
could cause Redis to perform controlled increments of up to 12 bytes past
the end of a stack-allocated buffer.
