Title
Mozilla Network Security Services加密问题漏洞
Description
Mozilla Firefox、Firefox ESR和Thunderbird都是由美国Mozilla基金会开发。Firefox是一款开源Web浏览器；Firefox ESR是Firefox的一个延长支持版本；Thunderbird是从Mozilla Application Suite中独立出来的一套电子邮件客户端软件。Mozilla Network Security Services（NSS）是一个函数库（网络安全服务库）。
多款Mozilla产品中使用的Mozilla NSS存在安全漏洞。由于程序未能正确确定TLS状态机的状态转换。允许攻击者以中间人方式攻击，并通过阻止消息来击败密码保护机制，具体表现为通过阻断服务器密钥的消息，也叫做“SMACK SKIP-TLS”的问题消除正向保密性。
