An unauthenticated remote attacker can exploit the vulnerability by sending PATH_CHALLENGE frames and manipulating the connection (e.g. by restricting the peer's congestion window size) so that PATH_RESPONSE frames can only be sent at the slower rate than they are received, leading to storage of path validation data in an unbounded queue.\n\n### Patches\nQuiche versions greater than 0.19.0 address this problem.\n\n### References\n[CVE-2023-6193](https://www.cve.org/CVERecord?id=CVE-2023-6193)\n[RFC 9000 Section 8.2](https://datatracker.ietf.org/doc/html/rfc9000#section-8.2)",
