微软1月补丁日回顾 | 新年新气象
微软发布1月份安全补丁，修复51个安全漏洞
微软在昨日例行更新中发布了1月份的安全补丁，修复了51个安全漏洞。其中有7个漏洞被标记为关键漏洞。
此次并没有出现已在野利用的漏洞，仅有一个漏洞是此前已披露的，这个漏洞是CVE-2019-0579。在9月的时候ZDI曾公开披露过这个漏洞（因为微软超过120天未修复漏洞），微软接着在10月的补丁日修复了这个漏洞，但仍有可以绕过的方式，此次则再次尝试Patch掉这个漏洞。
此前推特上疯狂丢0day的作者披露的漏洞暂还未修复完成，恐怕还需花些时日。
1月更新中几个重要的漏洞
CVE-2019-0550/0551 Hyper-V RCE漏洞
两个相似的漏洞，虽然归类为远程代码执行，但实际上是需要Guest权限下操作。近日360安全研究员因Hyper-V漏洞收获百万奖金，可见此类漏洞影响力与重要性。这两个漏洞同时也是去年Pwn2Own中用到的漏洞，并获得了25万美金奖励。
CVE-2019-0547 DHCP RCE漏洞
上次见到影响稍广的DHCP客户端漏洞是Linux上的CVE-2018-1111，差不多半年后Windows上也出现了类似的问题。此漏洞危害、利用评级非常高，被多家安全企业列入应用补丁的第一梯队。根据微软描述只需向客户端发送特殊的响应包即可触发漏洞，可能会遭到大规模的利用。
CVE-2019-0586 Exchange RCE漏洞
微软此次并未将其归类为关键漏洞，但此漏洞根据描述利用场景还是较为容易的，发送特殊的邮件即可在Exchange服务器System用户权限下实现代码执行。
