Vulnerability Title
Unbounded Memory Growth in the QUIC PATH_CHALLENGE Handler
Vulnerability Description
Issue summary: Remote peer may exhaust heap memory of the QUIC server or client by flooding it with packets containing PATH_CHALLENGE frames. Impact summary: A malicious remote peer can cause an unbounded memory allocation which can lead to an abnormal termination of the application acting as a QUIC client or server and a Denial of Service. A remote peer may exhaust heap memory by flooding the local QUIC stack with PATH_CHALLENGE frames. The local QUIC stack allocates a PATH_RESPONSE frame for every PATH_CHALLENGE it receives. The allocated PATH_RESPONSE frame gets freed only when the remote peer acknowledges reception of the PATH_RESPONSE frame which will not be done by a malicious peer. The FIPS modules in 4.0, 3.6, 3.5, 3.4, and 3.0 are not affected by this issue. The QUIC stack is outside of OpenSSL FIPS module boundary.

Vulnerability Title
OpenSSL 安全漏洞
Vulnerability Description
OpenSSL是OpenSSL团队的一个开源的能够实现安全套接层(SSLv2/v3)和安全传输层(TLSv1)协议的通用加密库。该产品支持多种加密算法,包括对称密码、哈希算法、安全散列算法等。 OpenSSL存在安全漏洞,该漏洞源于QUIC服务器或客户端处理PATH_CHALLENGE帧时内存分配不受限制,远程恶意对等方可通过发送大量PATH_CHALLENGE帧耗尽堆内存,导致应用异常终止和拒绝服务。
