high Nessus Plugin ID 138461

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4565529 or cumulative update 4565536. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists in the way that DirectWrite handles objects in memory. 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. 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 DirectWrite handles objects in memory. (CVE-2020-1409)

- An elevation of privilege vulnerability exists when the Windows Profile Service improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.
(CVE-2020-1360)

- 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-2020-1403)

- 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-2020-1468)

- A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted fonts. For all systems except Windows 10, an attacker who successfully exploited the vulnerability could execute code remotely. For systems running Windows 10, an attacker who successfully exploited the vulnerability could execute code in an AppContainer sandbox context with limited privileges and capabilities. An attacker could then install programs;
view, change, or delete data; or create new accounts with full user rights. There are multiple ways an attacker could exploit the vulnerability:
(CVE-2020-1436)

- An elevation of privilege vulnerability exists when the Windows UPnP Device Host improperly handles memory.
(CVE-2020-1354, CVE-2020-1430)

- An elevation of privilege vulnerability exists when the Windows Modules Installer improperly handles file operations. An attacker who successfully exploited this vulnerability could gain elevated privileges.
(CVE-2020-1346)

- An information disclosure vulnerability exists in Windows when the Windows Imaging Component fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user's system.
There are multiple ways an attacker could exploit this vulnerability: (CVE-2020-1397)

- A remote code execution vulnerability exists when Windows Address Book (WAB) improperly processes vcard files. (CVE-2020-1410)

- An elevation of privilege vulnerability exists when Group Policy Services Policy Processing improperly handle reparse points. An attacker who successfully exploited this vulnerability could overwrite a targeted file that would normally require elevated permissions.
(CVE-2020-1333)

- A remote code execution vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. An attacker who successfully exploited the 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-2020-1408)

- An elevation of privilege vulnerability exists when the Windows Event Logging Service improperly handles memory.
(CVE-2020-1365, CVE-2020-1371)

- An elevation of privilege vulnerability exists when Windows improperly handles calls to Advanced Local Procedure Call (ALPC). An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the local system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2020-1396)

- An elevation of privilege vulnerability exists in the way that the Windows Network Location Awareness Service handles objects in memory. An attacker who successfully exploited the vulnerability could allow an application with limited privileges on an affected system to execute code at a medium integrity level. (CVE-2020-1437)

- A remote code execution vulnerability exists in .NET Framework, Microsoft SharePoint, and Visual Studio when the software fails to check the source markup of XML file input. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the process responsible for deserialization of the XML content. (CVE-2020-1147)

- An elevation of privilege vulnerability exists when the Windows Cryptography Next Generation (CNG) Key Isolation service improperly handles memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2020-1359, CVE-2020-1384)

- An elevation of privilege vulnerability exists in the way that the Windows Network Connections Service handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-1373, CVE-2020-1390, CVE-2020-1427, CVE-2020-1428, CVE-2020-1438)

- An elevation of privilege vulnerability exists in the way that the Windows Function Discovery Service handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-1085)

- A remote code execution vulnerability exists in the way that Microsoft Graphics Components handle objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code on a target system. (CVE-2020-1412)

- A remote code execution vulnerability exists when the Windows Jet Database Engine improperly handles objects in memory. An attacker who successfully exploited this vulnerability could execute arbitrary code on a victim system. An attacker could exploit this vulnerability by enticing a victim to open a specially crafted file. The update addresses the vulnerability by correcting the way the Windows Jet Database Engine handles objects in memory. (CVE-2020-1400, CVE-2020-1401, CVE-2020-1407)

- An information disclosure vulnerability exists when the Windows kernel fails to properly initialize a memory address. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2020-1389, CVE-2020-1419)

- This security update corrects a denial of service in the Local Security Authority Subsystem Service (LSASS) caused when an authenticated attacker sends a specially crafted authentication request. A remote attacker who successfully exploited this vulnerability could cause a denial of service on the target system's LSASS service, which triggers an automatic reboot of the system. The security update addresses the vulnerability by changing the way that LSASS handles specially crafted authentication requests. (CVE-2020-1267)

- A remote code execution vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in the memory. 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-2020-1435)

- A remote code execution vulnerability exists in Microsoft Windows that could allow remote code execution if a .LNK file is processed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. (CVE-2020-1421)
