CVE-2023-46239

Summary

CVE-2023-46239 is a vulnerability affecting quic-go, an implementation of the QUIC protocol in Go. In versions 0.37.0 through 0.37.2, a remote attacker can cause a node to panic by sending a specifically crafted ACK frame following a CRYPTO frame during the QUIC handshake process. This allows the attacker to trigger a nil pointer dereference, resulting in a denial-of-service condition for the affected node. The vulnerability can be exploited easily, as completing the QUIC handshake requires only exchanging a few packets. Version 0.37.3 includes a patch to address this issue, while versions prior to 0.37.0 are not affected.
