A Malformed Lua script can crash Redis
Impact
An attacker attempting to load a specially crafted Lua script can cause NULL pointer dereference which will result with a crash of the redis-server process. This issue affects all versions of Redis.
Patches
The problem is fixed in Redis versions 7.0.0 and 6.2.7.
Workarounds
An additional workaround to mitigate this problem without patching the redis-server executable, if Lua scripting is not being used, is to block access to SCRIPT LOAD and EVAL commands using ACL rules.
