微软发布10月份安全补丁，修复49个安全漏洞
微软在昨日例行更新中发布了10月份的安全补丁，修复了49个安全漏洞。其中有12个漏洞被标记为关键漏洞，35个为重要漏洞，1个为中等严重漏洞，1个为低风险漏洞。
此次更新相比上月漏洞数量稍少，其中CVE-2018-8453漏洞在近日被APT组织FruityArmor用于攻击活动中，上月ZDI披露的CVE-2018-8423漏洞也被修复。
CVE-2018-8453 Win32k提权漏洞
CVE-2018-8453漏洞最初由卡巴斯基实验室观测到在野利用，经过后续研究发现其被APT组织FruityArmor用于攻击活动中，这也是该组织第三次利用0day漏洞（CVE-2016-3393、CVE-2018-5002 ）。不过此漏洞不能导致远程代码执行，只能用于感染机器后实现提权。
CVE-2018-8423 JET引擎远程代码执行漏洞
此漏洞是9月21日由一位安全研究员披露并公布PoC（微软未在120天内修复该漏洞），该漏洞最初由趋势科技研究员Lucas Leong发现，后经ZDI分析，影响当前受支持的所有Windows版本。在5月8日向微软提交后，微软于5月14日确认了该漏洞但一直没有进行修复，在达到披露期限后于上月安全研究员公开了该漏洞并放出了相关PoC。此漏洞在本次更新中已经成功修复。
