This month we got patches for 123 vulnerabilities. Of these, 17 are critical and 2 were previously disclosed.

Amongst critical vulnerabilities, there is a critical remote code execution (RCE) vulnerability (CVE-2020-1350) affecting Windows DNS Server on multiple Windows Server versions, including 2008, 2012, 2016 and 2019. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the Local System Account.

The DNS Server vulnerability scores a perfect 10 CVSS and is considered wormable, which means it has the potential to spread via malware vulnerable computers without user interaction. Microsoft advises everyone running DNS servers to apply the security update as soon as possible. For those unable to apply the patch right way, Microsoft recommends the application of a workaround, described on the CVE-2020-1350 vulnerability advisory details. The workarround consists on a registry modification and requires just the service restart - no need to reboot the OS. There is a special guidance for the DNS Server vulnerability including further details about the workaround here: https://support.microsoft.com/en-us/help/4569509/windows-dns-server-remote-code-execution-vulnerability

There is also a critical RCE vulnerability affecting Windows Graphics Device Interface (GDI) (CVE-2020-1435). An attacker could exploit this vulnerability by convincing users to view a specially crafted website or sending them an e-mail attachment with a malicious attachment. The CVSS score for this one is 8.80.

A third RCE worth mentioning in today’s diary affects Hyper-V RemoteFX vGPU (CVE-2020-1036). To exploit this vulnerability, an attacker could run a specially crafted application on a guest operating system, attacking certain third-party video drivers running on the Hyper-V host. This could then cause the host operating system to execute arbitrary code. There is no patch for this vulnerability yet. According to the vulnerability FAQ, If you are running Windows Server 2016 or Windows Server 2019, Microsoft recommends the use of  Discrete Device Assignment (DDA) as opposed to RemoteFX vGPU to enable graphics virtualization.
