CVE-2021-32762

An integer overflow issue leading to heap buffer overflow was found in the hiredis library. The “redis-cli” command-line tool and “redis-sentinel” service may be vulnerable to this flaw when parsing specially crafted, large multi-bulk network replies. This flaw allows a remote attacker to corrupt the heap and potentially trigger remote code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
