NVD Description

Note: Versions mentioned in the description apply only to the upstream redis:7/redis-devel package and not the redis:7/redis-devel package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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.
