2017-12-08漏洞描述
在使用 1024-bit moduli的AVX2 Montgomery乘法过程中存在一个溢出错误。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DH1024的攻击被认为是可行的，因为推断私钥信息所需的大部分工作可以在脱机状态下执行。这种攻击所需的资源数量将是巨大的。但是，要使对TLS的攻击有意义，服务器必须在多个客户机之间共享DH1024私钥，这在CVE-2016-0701之后就不再是一个选项了。这只影响支持AVX2的处理器，而不影响像Intel Haswell(第4代)这样的ADX扩展。注:该问题的影响与CVE-2017-3736、CVE-2017-3732、CVE-2015-3193相似。OpenSSL版本1.0.2-1.0.2m和1.1.0-1.1.0g受到影响。已修复OpenSSL 1.0.2n。由于这个问题的严重性较低，我们目前不会发布OpenSSL 1.1.0的新版本。当OpenSSL 1.1.0h可用时，将包含该修复程序。在OpenSSL git存储库的commit e502cc86d中也可以找到这个修复。解决建议
