Microsoft’s January “Fix” for Meltdown Made PCs Less Secure

You will definitely want to install March’s update!

Apparently the Jan/Feb fixes that were intended to help with the Intel processor’s vulnerability to “Meltdown”, opened up a security hole on Windows Server 2003 and Windows 7 machines that was even worse.

Researcher Ulf Frisk apparently discovered it, and it’s been said that the “fixes” left a vital kernel memory table read and WRITE-able for just normal user processes!

So, any malware on a vulnerable machine – as well as just any user who’s logged in could play with the OS’s memory map and get admin-level permissions as well as modify or extract any information in memory!
