微软发布12月份安全补丁，修复39个安全漏洞
微软在昨日例行更新中发布了12月份的安全补丁，修复了39个安全漏洞。其中有9个漏洞被标记为关键漏洞。
相比上月来说，修复的大大小小的漏洞数量少了三分之一，从一方面来说，可能这一个月漏洞数量稍少，不过从另一方面来说，也可能有不少漏洞都需要不止一个月的时间去修复，具体情况下月便可知晓。
微软连续第四个月补丁日修复0day漏洞
此次补丁日是微软连读第四个月修复已有在野利用的0day漏洞，与往常相比不同的是，这次的0day漏洞被两个APT组织接连使用。不过与上个月相同，这次0day漏洞还是由卡巴斯基发现的。此次修复的0day漏洞为CVE-2018-8611，虽然CVSS评级并不是非常高，但依然属于高危漏洞，可用于本地提权。除此之外，此次补丁日还修复了一个之前披露过的漏洞，为CVE-2018-8517，是.NET框架的拒绝服务漏洞。此漏洞可用来实现远程拒绝服务攻击。
少见的语音引擎漏洞
此次修复的漏洞中有一个漏洞比较有意思，是TTS引擎的漏洞。此漏洞为远程代码执行漏洞但微软并未公布漏洞细节，如有安全需求请务必关闭此服务的网络连接。
其他重要漏洞
此次有5个漏洞均与Chakra引擎有关，但根据前几日的消息微软准备使用Chromium打造新的Edge浏览器并与Win10分离为两个产品线，不知道Chakra引擎以后将何去何从。CVE-2018-8587、CVE-2018-8590、CVE-2018-8628则分别是Outlook、Word及Powerpoint的代码执行漏洞，在钓鱼攻击中可能会起到作用。
Adobe发布安全补丁修复87个漏洞
与微软相比Adobe可谓是修复了成吨的漏洞，其中也包含前几日APT攻击中用到的Flash 0day漏洞。关于这个漏洞，微软此次也发布了安全通告。
