Microsoft has recently announced that it has fixed around 90 vulnerabilities in its October 2020 Patch. Good news is, none of them has been exploited in any cyber-attacks, and many of the flaws had been publicly disclosed prior to the release of the patches.
These vulnerabilities have been classified as critical severity since their exploitation can disclose information or privilege escalation. The flaws impact the Windows and the .NET framework.
The .NET vulnerability enables an authenticated hacker to access the targeted system’s memory, especially the memory layout. Another flaw affects the Windows Error Reporting (WER) module, which can be utilized for privilege escalation.
