Vulnerability from cnvd

Title: OpenSSL拒绝服务漏洞

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中存在安全漏洞。攻击者可利用该漏洞借助较大的‘len’值导致未定义的指针运算，堆缓冲区边界检查中未正确使用指针，远程攻击者可利用该漏洞借助较大的‘len’值导致未定义的指针运算造成拒绝服务。

Severity: 高

Patch Name: OpenSSL设计漏洞的补丁
