Denial Of Service (DoS)

gRPC is vulnerable to Denial Of Service DoS. The vulnerability exists because the file descriptor is not properly handled, which leads to the termination of the connection between a proxy and a backend when a hpack table accounting errors occur, allowing an attacker to cause an application crash ...

Amazon Linux 2023 : grpc, grpc-cpp, grpc-data (ALAS2023-2023-282)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-282 advisory. 2023-10-12: CVE-2023-4785 was added to this advisory. When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table...

CVE-2023-33953

A flaw was found in the gRPC lib. This vulnerability allows hpack table accounting errors that could lead to unwanted disconnects between clients and servers in exceptional cases. This issue leads to Unbounded memory buffering in the HPACK parser and Unbounded CPU consumption in the HPACK parser...

CVE-2023-33953

CVE-2023-33953 concerns the gRPC HPACK parser. Multiple vectors cause denial-of-service via: (1) unbounded memory buffering due to header size checks behind string reads, (2) unbounded CPU due to per-input-block memory copies creating an 0(n^2) parsing loop, (3) HPACK varints that can start with ...

Important: grpc

Issue Overview: When gRPC HTTP2 stack raised a header size exceeded error, it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped, resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged, say, between a proxy and...
