Use After Free Affecting redis package, versions *

Note: Versions mentioned in the description apply only to the upstream redis package and not the redis package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

Redis is an open source, in-memory database that persists on disk. An authenticated user may use a specially crafted Lua script to manipulate the garbage collector and potentially lead to remote code execution. The problem is fixed in 7.4.2, 7.2.7, and 6.2.17. An additional workaround to mitigate the problem without patching the redis-server executable is to prevent users from executing Lua scripts. This can be done using ACL to restrict EVAL and EVALSHA commands.
