Redis allows denial-of-service due to malformed ACL selectors

Redis is an open source, in-memory database that persists on disk. An authenticated with sufficient privileges may create a malformed ACL selector which, when accessed, triggers a server panic and subsequent denial of service. The problem is fixed in Redis 7.2.7 and 7.4.2.
