Vulnerability Title
N/A
Vulnerability Description
The DH_check_pub_key function in crypto/dh/dh_check.c in OpenSSL 1.0.2 before 1.0.2f does not ensure that prime numbers are appropriate for Diffie-Hellman (DH) key exchange, which makes it easier for remote attackers to discover a private DH exponent by making multiple handshakes with a peer that chose an inappropriate number, as demonstrated by a number in an X9.42 file.

OpenSSL 信息泄露漏洞
Vulnerability Description
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 1.0.2f之前1.0.2版本的crypto/dh/dh_check.c文件中的‘DH_check_pub_key’函数存在安全漏洞，该漏洞源于程序没有确定Diffie-Hellman密钥交换是否使用合适的素数。远程攻击者可通过与使用不合适的素数的对等端建立多个握手过程，利用该漏洞发现DH指数。
