CVE:CVE-2009-0051
CNNVD:CNNVD-200901-065
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。
ZXID 没有正确处理函数OpenSSL DSA_verify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。
solution:Upgrade zxid zxid to a higher version than 0.29,0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,0.10,0.11,0.12,0.13,0.14,0.15,0.16,0.17,0.18,0.19,0.20,0.21,0.22,0.25,0.26,0.27,0.28,and avoid the version (,0.29],0.1,0.2,0.3,0.4,0.5,0.6,0.7,0.8,0.9,0.10,0.11,0.12,0.13,0.14,0.15,0.16,0.17,0.18,0.19,0.20,0.21,0.22,0.25,0.26,0.27,0.28
