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的s3_clnt.c文件中的‘ssl3_get_key_exchange’函数存在安全漏洞。远程攻击者可通过提供临时的RSA密钥利用该漏洞实施RSA-to-EXPORT_RSA降级攻击，加快暴力破解进度。以下版本受到影响：OpenSSL 0.9.8zd之前版本，1.0.0p之前1.0.0版本，1.

Source: CVE Program / CVE List V5
Vulnerability Description
The ssl3_get_key_exchange function in s3_clnt.c in OpenSSL before 0.9.8zd, 1.0.0 before 1.0.0p, and 1.0.1 before 1.0.1k allows remote SSL servers to conduct RSA-to-EXPORT_RSA downgrade attacks and facilitate brute-force decryption by offering a weak ephemeral RSA key in a noncompliant role, related to the "FREAK" issue. NOTE: the scope of this CVE is only client code based on OpenSSL, not EXPORT_RSA issues associated with servers or other TLS implementations.
