Connection Termination

grpc is vulnerable to Connection Termination. An attacker can terminate the connection between a HTTP2 proxy and the gRPC server by providing a -bin suffixed headers, which leads to a base64 encoding error, causing an application crash...

golang.org/x/net/http2: avoid quadratic complexity in HPACK decoding

A flaw was found in golang. A maliciously crafted HTTP/2 stream could cause excessive CPU consumption in the HPACK decoder, sufficient to cause a denial of service from a small number of requests...

Connection Confusion

grpc is vulnerable to Connection Confusion. The vulnerability exists when the gRPC HTTP2 stack raised a header size exceeded error, and it skipped parsing the rest of the HPACK frame, which caused any HPACK table mutations also to be skipped, resulting in the desynchronization of HPACK tables...

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...

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...

golang: net/http: excessive memory growth in a Go server accepting HTTP/2 requests

A flaw was found in the net/http library of the golang package. This flaw allows an attacker to cause excessive memory growth in a Go server accepting HTTP/2 requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache...

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...
