CVE-2023-32732

gRPC contains a vulnerability whereby a client can cause a termination of connection between a HTTP2 proxy and a gRPC server: a base64 encoding error for -bin suffixed headers will result in a disconnection by the gRPC server, but is typically allowed by HTTP2 proxies. We recommend upgrading beyo...

CVE-2023-1428 Denial-of-Service in gRPC

There exists an vulnerability causing an abort to be called in gRPC. The following headers cause gRPC's C++ implementation to abort when called via http2: te: x x != trailers :scheme: x x != http, https grpclbclientstats: x x == anything On top of sending one of those headers, a later header must...

CVE-2023-1428

CVE-2023-1428: gRPC for C++ is affected by a denial of service due to specific HTTP/2 header handling. When certain headers (for example te: x; :scheme: x; grpclb_client_stats: x) are sent and the total header size exceeds 8 KB, gRPC’s C++ implementation can abort(). The vulnerability is a NETWOR...

gRPC 安全漏洞

gRPC is a modern, open-source, high-performance Remote Procedure Call RPC framework from gRPC Open Source. A security vulnerability exists in gRPC, which stems from the ability to call abort functions via http2...

Uncontrolled Resource Consumption in LengthPrefixedMessageReader

Affected gRPC Swift clients and servers are vulnerable to uncontrolled resource consumption attacks. Excessive memory may be allocated when parsing messages. This can lead to a denial of service...

Incomplete Internal State Distinction in GRPCWebToHTTP2ServerCodec

Affected gRPC Swift servers are vulnerable to precondition failures when parsing certain gRPC Web requests. This may lead to a denial of service...

Denial of Service via reachable assertion

A grpc-swift server is vulnerable to a denial of service attack via a reachable assertion. This was 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 hig...

AZL-34782 CVE-2023-32067 affecting package grpc for versions less than 1.62.0-2

c-ares is an asynchronous resolver library. c-ares is vulnerable to denial of service. If a target resolver sends a query, the attacker forges a malformed UDP packet with a length of 0 and returns them to the target resolver. The target resolver erroneously interprets the 0 length as a graceful...

AZL-26922 CVE-2023-31130 affecting package grpc for versions less than 1.42.0-11

c-ares is an asynchronous resolver library. aresinetnetpton is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to...

AZL-26871 CVE-2023-31147 affecting package grpc for versions less than 1.42.0-10

c-ares is an asynchronous resolver library. When /dev/urandom or RtlGenRandom are unavailable, c-ares uses rand to generate random numbers used for DNS query ids. This is not a CSPRNG, and it is also not seeded by srand so will generate predictable output. Input from the random number generator i...
