For Microsoft [Update your Windows now]

Two security vulnerabilities fixes in Win32 CVE-2019-0803 and CVE-2019-0859.

CVE-2019-0803 | Win32k Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists in Windows when the Win32k component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system.

CVE-2019-0856 | Windows Remote Code Execution Vulnerability

A remote code execution vulnerability exists when Windows improperly handles objects in memory. An attacker who successfully exploited the vulnerability could take control of an affected system.

To exploit the vulnerability, an authenticated attacker could connect via the Windows Remote Registry Service, causing Windows to execute arbitrary code.

The security update addresses the vulnerability by correcting how Windows handles objects in memory.

CVE-2019-0791 | MS XML Remote Code Execution Vulnerability

A remote code execution vulnerability exists when the Microsoft XML Core Services MSXML parser processes user input. An attacker who successfully exploited the vulnerability could run malicious code remotely to take control of the user’s system.

To exploit the vulnerability, an attacker could host a specially crafted website designed to invoke MSXML through a web browser. However, an attacker would have no way to force a user to visit such a website.

Instead, an attacker would typically have to convince a user to either click a link in an email message or instant message that would then take the user to the website. When Internet Explorer parses the XML content, an attacker could run malicious code remotely to take control of the user’s system.

The update addresses the vulnerability by correcting how the MSXML parser processes user input.

For Adobe
