NVD Description

Note: Versions mentioned in the description apply only to the upstream redis-devel package and not the redis-devel package as distributed by Centos. See How to fix? for Centos:8 relevant fixed versions and status.

Redis is an in-memory data structure store. In all versions of redis-server with Lua scripting, an authenticated attacker can exploit the master-replica synchronization mechanism to trigger a use-after-free on replicas where replica-read-only is disabled or can be disabled, which may lead to remote code execution. A workaround is to prevent users from executing Lua scripts or avoid using replicas where replica-read-only is disabled. This is patched in version 8.6.3.
