CVE-2011-5094

一、漏洞信息
 漏洞编号：[CVE-2011-5094](https://nvd.nist.gov/vuln/detail/CVE-2011-5094)
 漏洞归属组件：[nss](https://gitee.com/src-openeuler/nss)
 漏洞归属的版本：3.94.0
 CVSS V3.0分值：
  BaseScore：4.3 Medium
  Vector：CVSS：3.0/AV:N/AC:M/Au:N/C:N/I:N/A:P
 漏洞简述：
  Mozilla Network Security Services (NSS) 3.x, with certain settings of the SSL_ENABLE_RENEGOTIATION option, does not properly restrict client-initiated renegotiation within the SSL and TLS protocols, which might make it easier for remote attackers to cause a denial of service (CPU consumption) by performing many renegotiations within a single connection, a different vulnerability than CVE-2011-1473.  NOTE: it can also be argued that it is the responsibility of server deployments, not a security library, to prevent or limit renegotiation when it is inappropriate within a specific environment

二、漏洞分析结构反馈
 影响性分析说明：
  这是个Dos攻击漏洞，由于服务器端的重新密钥协商的开销至少是客户端的10倍，因此攻击者可利用这个过程向服务器发起拒绝服务攻击。重协商是tls协议功能，这个cve跟nss无关；防止或限制特定环境中不合适的重协商是服务端设计的责任，和nss无关，服务端可以调用相关接口把重协商功能关闭。
