尚无明确在野利用证据，仍需结合暴露面评估

建议动作

优先检查厂商安全公告和参考链接中的修复版本；无法立即升级时，限制受影响服务暴露并加强监测。

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。OpenSSL DSA是其中的一个加密算法。 OpenSSL的crypto/dsa/dsa_ossl.c文件中的‘dsa_sign_setup’函数中存在安全漏洞，该漏洞源于程序没有正确确保执行constant-time操作。本地攻击者可通过实施边信道攻击利用该漏洞恢复私有的DSA密钥。
