Microsoft January 2018 Patch Tuesday

Microsoft, as expected included last weeks Meltdown/Spectre update in this months patch Tuesday. But note that in addition to these two flaws, we have a number of other "traditional" privilege escalation and even remote code execution flaws that are probably easier to exploit and should be treated probably with a higher priority. Regardless, I doubt that as many people will work overtime for these run of the mill flaws. For example:

CVE-2018-0788: A quick NVD search shows 15 different vulnerabilities for this Atmfd.dll. Some can even lead to code execution. But I doubt you will have this issue patched this week. Exploitation of CVE-2018-0788 can lead to code execution as administrator. Spectre/Meltdown only allow reading data.

CVE-2018-0773: An attacker may execute arbitrary code in the context of the user running the browser. Spectre, which was patched in many browser again only allows reading data.

and CVE-2018-0802, which is already being exploited.

So better get patching. It worked so well last month :)
