CVE-2024-37168 (CVSS 5.3)

Description

@grpc/grps-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to versions 1.10.9, 1.9.15, and 1.8.22, there are two separate code paths in which memory can be allocated per message in excess of the `grpc.max_receive_message_length` channel option: If an incoming message has a size on the wire greater than the configured limit, the entire message is buffered before it is discarded; and/or if an incoming message has a size within the limit on the wire but decompresses to a size greater than the limit, the entire message is decompressed into memory, and on the server is not discarded. This has been patched in versions 1.10.9, 1.9.15, and 1.8.22.
