Vulnerability from cnvd
Title: OpenSSL跨协议攻击漏洞
Description:
OpenSSL是一个实现安全套接层和安全传输层协议的通用开源加密库，可支持多种加密算法，包括对称密码、哈希算法、安全散列算法等。
OpenSSL 1.0.2及更早版本、1.0.1及更早版本存在跨协议攻击漏洞，当服务器使用了SSLv2协议和EXPORT加密套件，攻击者可利用漏洞对服务器的TLS会话信息进行破解；当客户端与不存在漏洞的服务器进行通信时，攻击者可以利用其他使用了SSLv2协议和EXPORT加密套件（即使服务器使用了不同的协议，例如SMTP，IMAP或者POP等协议）的服务器RSA密钥来对上述两者的通信数据进行破解。此漏洞被称为DROWN。
Severity: 高
Patch Name: OpenSSL跨协议攻击漏洞的补丁
