CVE-2023-1428

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-2023-32732

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...

Design/Logic Flaw

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-2023-32731 Information leak 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-2023-32731

CVE-2023-32731 involves a vulnerability in the gRPC HTTP/2 HPACK handling. When the HPACK header size exceeded error is raised, the stack skips parsing the remainder of the HPACK frame, causing HPACK table mutations to be ignored and desynchronizing the HPACK tables between sender and receiver. T...

CVE-2023-32732

CVE-2023-32732: gRPC vulnerability where a base64 encoding error for -bin suffixed headers can cause the gRPC server to terminate a connection with an HTTP/2 proxy, potentially affecting availability (LOW). Root cause described as a header encoding mishap that proxies may still allow, with remedi...

Denial of service via HTTP/2 HEADERS frames padding

A program using swift-nio-http2 is vulnerable to a denial of service attack, caused by a network peer sending a specially crafted HTTP/2 frame. This attack affects all swift-nio-http2 versions from 1.0.0 to 1.19.2. It is fixed in 1.20.0 and later releases. This vulnerability is caused by a logica...

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...
