quic-go vulnerable to pointer dereference that can lead to panic

High severity GitHub Reviewed Published Oct 27, 2023 in quic-go/quic-go • Updated Nov 9, 2023

Package

gomod github.com/quic-go/quic-go (Go)

Affected versions

>= 0.37.0, < 0.37.3

Patched versions

0.37.3

Description

quic-go is an implementation of the QUIC transport protocol in Go. By serializing an ACK frame after the CRYTPO that allows a node to complete the handshake, a remote node could trigger a nil pointer dereference (leading to a panic) when the node attempted to drop the Handshake packet number space.

Impact

An attacker can bring down a quic-go node with very minimal effort. Completing the QUIC handshake only requires sending and receiving a few packets.

Patches

v0.37.3 contains a patch. Versions before v0.37.0 are not affected.
