A stack-based buffer overflow in the _RdbLoadEntity function of the RDB graph decoders (src/serializers/decoders/*/decode_graph_entities.c) in FalkorDB before 4.18.4 allows a remote attacker who can issue Redis replication commands (for example, against an instance with no password configured) to cause a denial of service and possibly execute arbitrary code by supplying a crafted RDB stream with an attacker-controlled entity property count. The count sizes two variable-length arrays on the thread stack with no upper bound, and the decoder then fills them with attacker-supplied values.
