- Details

Redis contains a use-after-free vulnerability in the 'tlsProcessPendingData()' function, which handles the TLS pending-data list if Redis is configured with TLS support. A remote, unauthenticated attacker may be able to execute arbitrary commands with the privileges of the Redis server. Fixed in Redis 8.2.9, 8.4.6, 8.6.6, 8.8.2, and 8.10.1.
