⚡ TL;DR | Go Straight to the October 2020 Patch Tuesday Audit Report.

It’s October! This means that it’s cybersecurity awareness month. It’s also the second Tuesday of the month, which means that Microsoft is coming with a bunch of new software updates for their operating systems. In their latest patch, they included 87 fixes for various vulnerabilities and security problems in Microsoft Windows and other programs. Time to start patching!

They filled the October 2020 patch tuesday with fixes for 21 remote code execution vulnerabilities in products like Outlook, Excel and other Windows programs. Furthermore, there are 11 bugs that are marked ‘critical’, which makes them vulnerable for malicious software in order to take complete control of your system.

The most critical vulnerabilities

We start with CVE-2020-16898, which is a remote code execution vulnerability within Windows TCP/IP stack. If attackers leverage this by sending a malicious packet of data to that unpatched Windows system, they can take full control of your system. This flaw was named “Bad Neighbor” by McAfee.

Another critical vulnerability is CVE-2020-16947. This is a bug in Microsoft Outlook that can help an attacker gain access to your Windows system by just previewing a malicious email. Dustin Child stated that the preview pane is where the attack happens, you don’t even have to open the e-mail to become infected.

There are also two critical RCE vulnerabilities in the Microsoft SharePoint server. CVE-2020-16952 and CVE-2020-16951 are being exploited by a flaw in checking the source markup of the application. This allows the attacker to run arbitrary code in SharePoint.

Below, we made a table with the critical CVE codes for the Patch Tuesday October 2020 most critical CVE codes and their CVE description.
