Lua Use-After-Free may lead to remote code execution
Impact
An authenticated user may use a specially crafted Lua script to manipulate the garbage collector, trigger a use-after-free and potentially lead to remote code execution.
The problem exists in all versions of Redis with Lua scripting.
Workarounds
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.
