NTP 函数OpenSSL EVP_VerifyFinal 安全绕过漏洞

• CNNVD编号：CNNVD-200901-058
• 危害等级： 中危
  
• CVE编号： CVE-2009-0021
• 漏洞类型： 授权问题
• 发布时间： 2009-01-07
• 威胁类型： 远程
• 更新时间： 2009-05-16
• 厂        商： ntp
• 漏洞来源： Google安全小组

漏洞简介

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。
