GitHub Vulnerability Alerts

GHSA-m425-mq94-257g

Impact

In affected releases of gRPC-Go, it is possible for an attacker to send HTTP/2 requests, cancel them, and send subsequent requests, which is valid by the HTTP/2 protocol, but would cause the gRPC-Go server to launch more concurrent method handlers than the configured maximum stream limit.

Patches

This vulnerability was addressed by #​6703 and has been included in patch releases: 1.56.3, 1.57.1, 1.58.3. It is also included in the latest release, 1.59.0.

Along with applying the patch, users should also ensure they are using the grpc.MaxConcurrentStreams server option to apply a limit to the server's resources used for any single connection.

Workarounds

None.

#​6703

CVE-2023-44487

swift-nio-http2 is vulnerable to a denial-of-service vulnerability in which a malicious client can create and then reset a large number of HTTP/2 streams in a short period of time. This causes swift-nio-http2 to commit to a large amount of expensive work which it then throws away, including creating entirely new Channels to serve the traffic. This can easily overwhelm an EventLoop and prevent it from making forward progress.

swift-nio-http2 1.28 contains a remediation for this issue that applies reset counter using a sliding window. This constrains the number of stream resets that may occur in a given window of time. Clients violating this limit will have their connections torn down. This allows clients to continue to cancel streams for legitimate reasons, while constraining malicious actors.

Release Notes

grpc/grpc-go (google.golang.org/grpc)

v1.56.3: Release 1.56.3

Compare Source

Security

• server: prohibit more than MaxConcurrentStreams handlers from running at once (CVE-2023-44487)

  In addition to this change, applications should ensure they do not leave running tasks behind related to the RPC before returning from method handlers, or should enforce appropriate limits on any such work.

v1.56.2: Release 1.56.2

Compare Source

• status: To fix a panic, status.FromError now returns an error with codes.Unknown when the error implements the GRPCStatus() method, and calling GRPCStatus() returns nil. (#​6374)

v1.56.1: Release 1.56.1

Compare Source

• client: handle empty address lists correctly in addrConn.updateAddrs

v1.56.0: Release 1.56.0

Compare Source
