Microsoft Releases April 2019 Security Updates — Two Flaws Under Active Attack


Microsoft today released its April 2019 software updates to address a total of 74 CVE-listed vulnerabilities in its Windows operating systems and other products, 13 of which are rated critical and rest are rated Important in severity.

April 2019 security updates address flaws in Windows OS, Internet Explorer, Edge, MS Office, and MS Office Services and Web Apps, ChakraCore, Exchange Server, .NET Framework and ASP.NET, Skype for Business, Azure DevOps Server, Open Enclave SDK, Team Foundation Server, and Visual Studio.

None of the vulnerabilities addressed this month by the tech giant were disclosed publicly at the time of release, leaving the two recently disclosed zero-day flaws in Internet Explorer and Edge browsers still open for hackers.

However, two new privilege escalation vulnerabilities, which affect all supported versions of the Windows operating system, have been reported as being actively exploited in the wild.

Both rated as important, the flaws (CVE-2019-0803 and CVE-2019-0859) reside in the Win32k component of Windows operating system that could be exploited by attackers to run arbitrary code in kernel mode on a targeted computer.
