OpenSSL sigalgs 拒绝服务漏洞
Source: CNNVD (China National Vulnerability Database)
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 1.0.2及之前版本的t1_lib.c文件中的sigalgs实现过程中存在安全漏洞。当程序在重新协商过程中时，远程攻击者可借助在ClientHello消息中使用无效的signature_algorithms扩展利用该漏洞造成拒绝服务（空指针逆向引用和守护进程崩溃）。
