CVE-2019-0614 | Windows GDI Information Disclosure Vulnerability

An information disclosure vulnerability exists when the Windows GDI component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.

There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit an untrusted webpage.

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

CVE-2019-0702 | Windows Kernel Information Disclosure Vulnerability

An information disclosure vulnerability exists when the Windows kernel improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system.

To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to execute code or to elevate user rights directly, but it could be used to obtain information that could be used to try to further compromise the affected system.

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

CVE-2019-0703 | Windows SMB Information Disclosure Vulnerability

An information disclosure vulnerability exists in the way that the Windows SMB Server handles certain requests. An authenticated attacker who successfully exploited this vulnerability could craft a special packet, which could lead to information disclosure from the server.

The security update addresses the vulnerability by correcting how Windows SMB Server handles authenticated requests.

CVE-2019-0776 | Win32k Information Disclosure Vulnerability

An information disclosure vulnerability exists when the win32k component improperly provides kernel information. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.

To exploit the vulnerability, an attacker would have to either log on locally to an affected system, or convince a locally authenticated user to execute a specially crafted application.
