Windows 7 Total Meltdown Vulnerability
In January, Intel and AMD released patches for severe processor level vulnerabilities that revealed flaws in chip architecture for the last 20 years. The vulnerabilities lie in the speculative processing and kernel page table isolation libraries, and allow an attacker to access privileged memory in a read-only mode. In the January and Februaru Patch Tuesday updates for Windows, Microsoft patched part of the vulnerability. Their patch however, opened up a far more concerning vulnerability, which allows an attacker to not only read out the entire memory stack, but also modify sections and inject malicious code.
