Descripción
*** Pendiente de traducción *** Allocation of Resources Without Limits or Throttling vulnerability in elixir-grpc grpc allows unauthenticated attackers to exhaust the BEAM&#39;s memory and crash the server by streaming a large or slow-trickle unary request body.<br />
<br />
&#39;Elixir.GRPC.Server.Adapters.Cowboy.Handler&#39;:read_full_body/3 (lib/grpc/server/adapters/cowboy/handler.ex) accumulates every received chunk into a single growing binary with no size cap. Additionally, when the client omits the grpc-timeout header, the per-chunk read timeout resolves to :infinity, allowing a slow-trickle client to keep the connection alive indefinitely while memory grows. A single connection is sufficient to exhaust server memory and crash the node.<br />
<br />
This issue affects grpc from 0.3.1 before 1.0.0.
