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crypto/bn/bn_gf2m.c文件中的‘BN_GF2m_mod_inv’函数存在安全漏洞，该漏洞源于程序没有正确处理ECParameters结构体。远程攻击者可借助使用Elliptic Curve算法的会话利用该漏洞造成拒绝服务（无限循环）。以下版本受到影响：OpenSSL 0.9.8s

Vulnerability Description
The BN_GF2m_mod_inv function in crypto/bn/bn_gf2m.c in OpenSSL before 0.9.8s, 1.0.0 before 1.0.0e, 1.0.1 before 1.0.1n, and 1.0.2 before 1.0.2b does not properly handle ECParameters structures in which the curve is over a malformed binary polynomial field, which allows remote attackers to cause a denial of service (infinite loop) via a session that uses an Elliptic Curve algorithm, as demonstrated by an attack against a server that supports client authentication.
