CVE-2024-37168Network attack vector

Denial of service via oversized message allocation

Published Jun 10, 2024 · Updated Aug 2, 2024

Denial of service in affected gRPC for Node.js releases allows remote attackers to exhaust memory via crafted incoming messages. Receive paths buffer an over-limit wire message before rejection and fully decompress a within-limit message without enforcing the configured post-decompression limit. A network-reachable gRPC peer must accept the crafted message; the resulting memory pressure can interrupt the hosting process.
