KB4530715: Windows 10 Version 1809 and Windows Server 2019 December 2019 Security Update

high Nessus Plugin ID 131932

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4530715.
It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system. (CVE-2019-1471)

- 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-2019-1484)

- A denial of service vulnerability exists in Remote Desktop Protocol (RDP) when an attacker connects to the target system using RDP and sends specially crafted requests. An attacker who successfully exploited this vulnerability could cause the RDP service on the target system to stop responding. (CVE-2019-1453)

- 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 users system. (CVE-2019-1472, CVE-2019-1474)

- An elevation of privilege vulnerability exists when the Windows AppX Deployment Server improperly handles junctions. (CVE-2019-1483)

- 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 users system. (CVE-2019-1469)

- A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited this vulnerability could take control of the affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2019-1468)

- 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-2019-1465, CVE-2019-1466, CVE-2019-1467)

- An elevation of privilege vulnerability exists when the Windows Printer Service improperly validates file paths while loading printer drivers. An authenticated attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges.
(CVE-2019-1477)

- An elevation of privilege vulnerability exists when Windows AppX Deployment Service (AppXSVC) improperly handles hard links. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could then install programs; view, change or delete data. (CVE-2019-1476)

- An information disclosure vulnerability exists when Windows Hyper-V on a host operating system fails to properly validate input from an authenticated user on a guest operating system. (CVE-2019-1470)

- A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2019-1485)

- A security feature bypass vulnerability exists when Microsoft Defender improperly handles specific buffers.
An attacker could exploit the vulnerability to trigger warnings and false positives when no threat is present.
(CVE-2019-1488)
