Fixed In Version: redis 6.2.6, redis 6.0.16, redis 5.0.14
Doc Type: If docs needed, set a value
Doc Text:
A heap buffer overflow was found in redis. Specially crafted Lua scripts executing in Redis cause the heap-based Lua stack to overflow due to incomplete checks for this condition. This flaw allows a remote attacker to corrupt the heap and potentially trigger remote code execution. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.

Description Pedro Sampaio 2021-10-05 18:47:02 UTC 
Redis is an open source, in-memory database that persists on disk. In affected versions specially crafted Lua scripts executing in Redis can cause the heap-based Lua stack to be overflowed, due to incomplete checks for this condition. This can result with heap corruption and potentially remote code execution. This problem exists in all versions of Redis with Lua scripting support, starting from 2.6. The problem is fixed in versions 6.2.6, 6.0.16 and 5.0.14. For users unable to update 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.
