Vulnerability Title
Unbounded queuing of path validation messages in cloudflare-quiche
Vulnerability Description
quiche v. 0.15.0 through 0.19.0 was discovered to be vulnerable to unbounded queuing of path validation messages, which could lead to excessive resource consumption. QUIC path validation (RFC 9000 Section 8.2) requires that the recipient of a PATH_CHALLENGE frame responds by sending a PATH_RESPONSE. 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. Quiche versions greater than 0.19.0 address this problem.

Vulnerability Title
quiche 安全漏洞
Vulnerability Description
quiche是Cloudflare开源的一个 IETF 指定的 QUIC 传输协议和 HTTP/3 的实现。 quiche v0.15.0 到 0.19.0版本存在安全漏洞，该漏洞源于QUIC 路径验证要求 PATH_CHALLENGE 帧的接收者通过发送 PATH_RESPONSE 进行响应，远程攻击者利用该漏洞可以通过发送 PATH_CHALLENGE 帧操纵连接，使路径验证消息无限制排队，导致资源消耗过多。
