Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

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。
