A flaw was found in Redis. This vulnerability, a use-after-free, exists within the `tlsProcessPendingData()` function, which manages the Transport Layer Security (TLS) pending-data list when Redis is configured with TLS support. A remote, unauthenticated attacker could exploit this to execute unauthorized commands with the same privileges as the Redis server.
