GHSA-6628-Q6J9-W8VG gRPC Reachable Assertion issue

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...

GHSA-9HXF-PPJV-W6RQ gRPC connection termination issue

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...

Connection confusion in gRPC

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 a backend, this...

CVE-2023-32732

A flaw was found in gRPC, which is vulnerable to a denial of service, caused by a base64 encoding error for "-bin" suffixed headers. By sending a specially crafted request, a remote attacker can cause a termination of the connection between an HTTP2 proxy and a gRPC server, resulting in a denial ...

CVE-2023-1428

A flaw was found in the gRPC library. Affected versions of this package are vulnerable to a reachable assertion, causing the abort function to be called and resulting in a denial of service. Mitigation Mitigation for this issue is either not available or the currently available options do not mee...

CVE-2023-32731

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...
