CVE-2024-7596

Proposed Generic UDP Encapsulation GUE IETF Draft do not validate or verify the source of a network packet allowing an attacker to spoof and route arbitrary traffic via an exposed network interface that can lead to spoofing, access control bypass, and other unexpected network behaviors. This can ...

CVE-2024-7596

CVE-2024-7596 / CVE-2025-23018 (and related CVEs) involve tunneling protocols that do not validate the source of a network packet. Specifically: The GRE/GRE6 (CVE-2024-7595) and Propose d Generic UDP Encapsulation (GUE) (CVE-2024-7596) cases describe lack of source verification in encapsulated tr...

quic-go affected by an ICMP Packet Too Large Injection Attack on Linux

Impact An off-path attacker can inject an ICMP Packet Too Large packet. Since affected quic-go versions used IPPMTUDISCDO, the kernel would then return a "message too large" error on sendmsg, i.e. when quic-go attempts to send a packet that exceeds the MTU claimed in that ICMP packet. By setting...

CVE-2024-52811 Acks not validated before logged to qlog leads to buffer overflow in ngtcp2

The ngtcp2 project is an effort to implement IETF QUIC protocol in C. In affected versions acks are not validated before being written to the qlog leading to a buffer overflow. In ngtcp2conn::connrecvpkt for an ACK, there was new logic that got added to skip connrecvack if an ack has already been...

CVE-2024-45311

Quinn is a pure-Rust, async-compatible implementation of the IETF QUIC transport protocol. As of quinn-proto 0.11, it is possible for a server to accept, retry, refuse, or ignore an Incoming connection. However, calling retry on an unvalidated connection exposes the server to a likely panic in th...
