An integer overflow issue was found in redis in the underlying string library. The vulnerability involves changing the default “proto-max-bulk-len” configuration parameter to a very large value and constructing specially crafted network payloads or commands. 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.
Mitigation
The flaw can be mitigated by disallowing usage of the CONFIG SET command via ACL configuration. This will prevent clients from setting the proto-max-bulk-len configuration parameter. Please see <https://redis.io/topics/acl> for more information on how to do this.
