CVSS: 7.5EPSS: 0%CPEs: 1EXPL: 0CVE-2022-24777 – Denial of Service via reachable assertion in grpc-swift
https://notcve.org/view.php?id=CVE-2022-24777
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. • https://github.com/grpc/grpc-swift/commit/858f977f2a51fca2292f384cf7a108dc2e73a3bd https://github.com/grpc/grpc-swift/security/advisories/GHSA-r6ww-5963-7r95 • CWE-617: Reachable Assertion •

HTTP2ToRawGRPCServerCodec in gRPC Swift 1.1.1 and earlier allows remote attackers to deny service via the delivery of many small messages within a single HTTP/2 frame, leading to Uncontrolled Recursion and stack consumption. La función HTTP2ToRawGRPCServerCodec en gRPC Swift versiones 1.1.1 y anteriores, permite a atacantes remotos denegar el servicio por medio de la entrega de muchos mensajes pequeños dentro de una sola trama HTTP/2, conllevando a una Recursión no controlada y un consumo de la pila • https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=35274 https://github.com/grpc/grpc-swift/releases https://github.com/grpc/grpc-swift/security/advisories/GHSA-4rhq-vq24-88gw • CWE-674: Uncontrolled Recursion •
