Patch Tuesday, February 2019

With today's Patch Tuesday for February, things are back to normal with patches for 76 CVEs and four advisories. Twenty of the CVEs are rated "Critical," 53 are rated "Important," and three are rated "Moderate." On the "Critical" list you'll find the typical remote code execution (RCE) vulnerabilities in the MS Scripting Engine and the Windows Graphics Device Interface (GDI). More troubling are RCE vulnerabilities for SharePoint and Windows DHCP Servers. While there is currently no public exploit for these vulnerabilities, an exploit could allow an attacker to take control of the server.

Among the CVEs rated as "Important," there are a couple of new packages that stand out. The Azure IoT Java SDK has two vulnerabilities that are patched, an Information Disclosure and Elevation of Privilege. The privilege escalation vulnerability rests in how the SDK generates symmetric keys for encryption. The lack of proper randomness would allow an attacker to derive the keys from the way they are created and use them to access a user's IoT hub. Several vulnerabilities affect Security modules in Windows including Windows Defender Firewall that improperly applies security profiles for connections that incorrectly applies firewall profiles where the system is connected to both an ethernet network and a cellular network.

Among the four general advisories, you'll find updates for Adobe Flash, Servicing Stack Updates (SSU) which affect how fixes and patches are delivered to your system, and two update advisories for Microsoft Exchange Server. One is an elevation of privilege vulnerability and the other rests in how Exchange Server implements libraries from Oracle Outside.

So get to patching, and we'll see you next month.
