Redis is an open source, in-memory database that persists on disk. Versions8.2.1 and below allow an authenticated user to use a specially crafted LUAscript to read out-of-bound data or crash the server and subsequent denialof service. The problem exists in all versions of Redis with Lua scripting.This issue is fixed in version 8.2.2. To workaround this issue withoutpatching the redis-server executable is to prevent users from executing Luascripts. This can be done using ACL to block a script by restricting boththe EVAL and FUNCTION command families.
