Elixir protobuf is a pure Elixir implementation of Google Protobuf. From 0.8.0 until 0.16.1, services that decode attacker-controlled protobuf bytes with Protobuf.Decoder can be taken offline when the schema contains a self-referential or cyclic message type. In lib\/protobuf\/decoder.ex, Protobuf.Decoder.value_for_field\/3 handles an embedded?: true field by recursively entering the decode \/ build_message \/ handle_value \/ value_for_field call chain without enforcing a nesting-depth limit. Deeply nested embedded fields retain non-tail recursive frames, allowing a comparatively small request to consume substantial CPU and memory, pin a BEAM scheduler, and exhaust the node. This issue is fixed in version 0.16.1.<\/p>\n","protected":false},"excerpt":{"rendered":"
