Vulnerability from cnvd
Title: OpenSSL拒绝服务漏洞（CNVD-2016-01479）
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 1.0.1s之前1.0.1版本和1.0.2g之前1.0.2版本的crypto/bio/b_print.c文件中的‘doapr_outch’函数存在安全漏洞，该漏洞源于程序未能验证内存分配是否成功。远程攻击者可借助较长的字符串利用该漏洞造成拒绝服务（越边界写入或内存消耗）。
Severity: 高
