CVE-2022-24777

Estado: ModificadaAlta (7.5)—

grpc-swift is the Swift language implementation of gRPC, a remote procedure call (RPC) framework. Prior to version 1.7.2, a grpc-swift server is vulnerable to a denial of service attack via a reachable assertion. This is due to incorrect logic when handling GOAWAY frames. The attack is low-effort: it takes very little resources to construct and send the required sequence of frames. The impact on availability is high as the server will crash, dropping all in flight connections and requests. This issue is fixed in version 1.7.2. There are currently no known workarounds.

En versiones anteriores a 1.7.2, un servidor grpc-swift es vulnerable a un ataque de denegación de servicio por medio de una aserción alcanzable. Esto es debido a una lógica incorrecta cuando son manejadas las tramas GOAWAY. El ataque es de bajo esfuerzo: son necesarios muy pocos recursos para construir y enviar la secuencia de tramas requerida.
