Vulnerability from cnvd

Title: OpenSSL加密算法破解漏洞

Description:

OpenSSL是一个实现安全套接层和安全传输层协议的通用开源加密库,可支持多种加密算法,包括对称密码、哈希算法、安全散列算法等。

OpenSSL存在一处加密算法破解漏洞,当满足一定条件,攻击者可以通过服务器发送大量的握手请求,当有足够多的计算数据完成后,攻击者可以获取部分密钥值,并结合其结果与中国剩余定理最终推导出解密密钥。

Severity:

Patch Name: OpenSSL加密算法破解漏洞的补丁

Patch Description:

OpenSSL是一个实现安全套接层和安全传输层协议的通用开源加密库,可支持多种加密算法,包括对称密码、哈希算法、安全散列算法等。

OpenSSL存在一处加密算法破解漏洞,当满足一定条件,攻击者可以通过服务器发送大量的握手请求,当有足够多的计算数据完成后,攻击者可以获取部分密钥值,并结合其结果与中国剩余定理最终推导出解密密钥。目前,供应商发布了安全公告及相关补丁信息,修复了此漏洞。
