Microsoft released its monthly updates security Tuesday Patch yesterday . The December 2020 Patch Tuesday fixes 58 vulnerabilities in more than 10 of the company's products and services .
The number of vulnerabilities being fixed is relatively small compared to the company's usual security updates, but some of the bugs are still very serious.
In December's Patch Tuesday, Microsoft is patching 22 vulnerabilities that allow remote code execution (RCE), which need to be addressed immediately because they can be easily exploited by criminals, either over the Internet or from a local network, without requiring users to do anything.
RCE vulnerabilities have been identified in Microsoft products, including Windows NTFS, Exchange Server, Microsoft Dynamics, Excel, PowerPoint, SharePoint, Visual Studio, and Hyper-V.
However, the RCE vulnerabilities that have been assessed as more severe and can be exploited more easily are those affecting Exchange Server (CVE-2020-17143, CVE-2020-17144, CVE-2020-17141, CVE-2020-17117, CVE-2020-17132, and CVE-2020-17142) and SharePoint (CVE-2020-17118 and CVE-2020-17121).
Microsoft recommends that these errors be fixed immediately, as, due to their nature, Exchange and SharePoint systems are typically connected to the Internet and, therefore, easier to target by criminals.
Another major bug fixed in this month's December Patch Tuesday is a flaw in Hyper-V, which is used to host virtual machines. Using a malicious SMB packet, this bug could allow remote attackers to compromise virtual sandboxed environments, which are supposedly protected by Hyper-V.
