Microsoft Patch Tuesday January 2017
Start of this new year, Meltdown and Spectre kept us busy. Today Microsoft released regular patches fixing a total of 23 vulnerabilities. Among these Microsoft rated one CVE as Critical, 20 as Important, one as Moderate and last one as Low. Microsoft also released 2 advisories for Adobe and Microsoft Office. Out of these 23 vulnerabilities, 15 lead to Remote Code Execution.

In January 2018, Microsoft released patches for total 56 vulnerabilities (CVE’s) and 3 advisories, which includes out of band updates from last week and now January Patch Tuesday.


Microsoft Office received a major share of security updates this month. The most important of these is the 0-day vulnerability in Equation Editor, a component of Microsoft Office. This vulnerability is due to the way objects are handled in memory, aka “Microsoft Office Memory Corruption Vulnerability” and can lead to remote code execution on the affected systems. For successful exploitation, an attacker has to convince users to open malicious office file by making the user to download and open the file via an email or instant message. Successful exploitation of this vulnerability could allow an attacker to run arbitrary code in the context of the logged in user. Microsoft addressed this 0-day by removing some of the Equation Editor’s functionality.

NOTE: Test and deploy all the patches released to mitigate Meltdown and Spectre, as there could be a performance related problems since it involves BIOS level patches.
