官方补丁披露时间
2017-11-03漏洞描述
OpenSSL中的 x86_64 Montgomery squaring procedure在1.0.2m之前和1.1.0g之前存在一个进位传播错误。不影响EC算法。分析表明，由于这一缺陷而对RSA和DSA进行攻击将非常困难，而且不太可能。对DH的攻击被认为是可行的(尽管非常困难)，因为推断关于私有密匙的信息所需的大部分工作可能在脱机情况下执行。此类攻击所需的资源数量将非常大，并且可能只对有限数量的攻击者开放。在具有持久的DH参数和在多个客户机之间共享的私有密钥的场景中，攻击者还需要使用目标私有密钥在线访问未修补的系统。这只会影响到支持BMI1、BMI2和ADX扩展的处理器，比如Intel Broadwell(第5代)以及后来的AMD Ryzen。解决建议
