Vulnerability Description
NTP 4.2.4 before 4.2.4p5 and 4.2.5 before 4.2.5p150 does not properly check the return value from the OpenSSL EVP_VerifyFinal function, which allows remote attackers to bypass validation of the certificate chain via a malformed SSL/TLS signature for DSA and ECDSA keys, a similar vulnerability to CVE-2008-5077.

Vulnerability Title
NTP 函数OpenSSL EVP_VerifyFinal 安全绕过漏洞
Vulnerability Description
NTP (Network Time Protocol)是一款客户端用于与时间服务器同步日期和时间的协议。 OpenSSL是OpenSSL团队开发的一个开源的能够实现安全套接层（SSL v2/v3）和安全传输层（TLS v1）协议的通用加密库，它支持多种加密算法，包括对称密码、哈希算法、安全散列算法等。 NTP 没有正确处理函数OpenSSL EVP_VerifyFinal返回值，使系统存在安全绕过漏洞。远程攻击者可以通过为DSA和ECDSA key伪造SSL/TLS签名绕过证书链表符合性检查。
