Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4561673 or cumulative update 4561666. It is, therefore, affected by multiple vulnerabilities :

 - An elevation of privilege vulnerability exists in the way that the wlansvc.dll handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
 (CVE-2020-1270)

 - 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 users 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-2020-1348)

 - A remote code execution vulnerability exists when Microsoft Windows OLE fails to properly validate user input. An attacker could exploit the vulnerability to execute malicious code. (CVE-2020-1281)
