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.
