AZL-38785 CVE-2023-45288 affecting package azcopy for versions less than 10.25.1-1

An attacker may cause an HTTP/2 endpoint to read arbitrary amounts of header data by sending an excessive number of CONTINUATION frames. Maintaining HPACK state requires parsing and processing all HEADERS and CONTINUATION frames on a connection. When a request's headers exceed MaxHeaderBytes, no...

AZL-39460 CVE-2024-28182 affecting package nghttp2 for versions less than 1.57.0-2

nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK...

HPACK decoder panics on invalid input

Due to insufficient checking of input data, decoding certain data sequences can lead to Decoder::decode panicking rather than returning an error. Example code that triggers this vulnerability looks like this: rust use hpack::Decoder; pub fn main let input = &0x3f; let mut decoder = Decoder::new;...

GHSA-CFGP-2977-2FMM 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...
