Patch Tuesday, March 2019

This month's Patch Tuesday brings with it four advisories and patches for 64 CVEs including a patch for a zero-day actively exploited in the wild. The rating of the CVEs breaks down into 17 Critical, 45 Important, one Low, and one Moderate. Among the CVEs rated "Critical" are three Remote Code Execution (RCE) vulnerabilities for the Windows DHCP Client which could affect any Windows workstation that gets an IP address automatically from the network. Similarly, the Windows TFTP Server is getting a fix for an RCE vulnerability which could be exploited to allow an attacker to take control of the system that deploys operating system images and configuration information to network devices.

Under the CVEs rated "Important" you'll find patches for two Windows privilege escalation vulnerabilities disclosed last week by Google (CVE-2019-0797 and CVE-2019-0808). These vulnerabilities were being exploited in concert with a code execution vulnerability in Google's Chrome web browser. Chaining the vulnerabilities together results in an attack that can execute code and escalate its system privilege to take complete control of the victim's system. Although none of the other vulnerabilities are currently known to have any exploits available, there's a wide selection of software and Windows components affected this month. That includes the usual suspects like Microsoft Office, Internet Explorer, Edge, and the various scripting engines employed. In addition, you'll find patches for Active Directory, Visual Studio, Windows Hyper-V, SharePoint, Windows Subsystem for Linux, Skype for Business and Lync.

There are also four advisories included in this release which includes the March Adobe Flash Update and the newest Servicing Stack Updates (SSU) which makes sure the infrastructure to apply updates and patches is itself up to date. The other two advisories are a SHA-2 Code Sign Support Advisory, which expands the ability to verify SHA-2 Code Signing to Windows 7 SP1 and Windows Server 2008 R2 SP1, and an advisory covering the best practices for sharing a single user account across multiple users.

We'll see you next month, but until then get to patching and stay safe!
