NewCVE-2024-53259 Â (opens in a new tab)How to fix?
Upgrade github.com/quic-go/quic-go to version 0.48.2 or higher.
Overview
Affected versions of this package are vulnerable to Insufficient Verification of Data Authenticity through the sendmsg process. An attacker can disrupt a QUIC connection by injecting an ICMP Packet Too Large packet, which causes the kernel to return a "message too large" error.
Note: This is only exploitable if the attacker knows the client's IP and port tuple, assuming knowledge of the server's IP and port as well.
Workaround
This vulnerability can be mitigated by using iptables to drop ICMP Unreachable packets.
