Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4541500 or cumulative update 4540688. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists when Internet Explorer improperly accesses 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-2020-0824)

- An elevation of privilege vulnerability exists in Windows Installer because of the way Windows Installer handles certain filesystem operations. (CVE-2020-0814, CVE-2020-0842, CVE-2020-0843)

- An elevation of privilege vulnerability exists when the Windows Background Intelligent Transfer Service (BITS) improperly handles symbolic links. An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status.
(CVE-2020-0787)

- An information disclosure vulnerability exists when Windows Network Connections Service fails to properly handle objects in memory. An attacker who successfully exploited the vulnerability could potentially disclose memory contents of an elevated process. (CVE-2020-0871)

- A tampering vulnerability exists when Microsoft IIS Server improperly handles malformed request headers. An attacker who successfully exploited the vulnerability could cause a vulnerable server to improperly process HTTP headers and tamper with the responses returned to clients. (CVE-2020-0645)

- 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. (CVE-2020-0788, CVE-2020-0877, CVE-2020-0887)

- 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-2020-0778, CVE-2020-0802, CVE-2020-0803, CVE-2020-0804, CVE-2020-0845)

- An elevation of privilege vulnerability exists when Connected User Experiences and Telemetry Service improperly handles file operations. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could exploit this vulnerability by running a specially crafted application on the victim system. The security update addresses the vulnerability by correcting how the Connected User Experiences and Telemetry Service handles file operations. (CVE-2020-0844)

- 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-2020-0684)

- An elevation of privilege vulnerability exists when the Windows User Profile Service (ProfSvc) improperly handles symlinks. An attacker who successfully exploited this vulnerability could delete files and folders in an elevated context. (CVE-2020-0785)

- An information disclosure vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in memory, allowing an attacker to retrieve information from a targeted system. By itself, the information disclosure does not allow arbitrary code execution; however, it could allow arbitrary code to be run if the attacker uses it in combination with another vulnerability. (CVE-2020-0874, CVE-2020-0879)

- An elevation of privilege vulnerability exists in Windows Error Reporting (WER) when WER handles and executes files. The vulnerability could allow elevation of privilege if an attacker can successfully exploit it.
An attacker who successfully exploited the vulnerability could gain greater access to sensitive information and system functionality. (CVE-2020-0806)

- 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-2020-0774, CVE-2020-0880, CVE-2020-0882)

- 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-2020-0881, CVE-2020-0883)

- 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 a 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 update addresses the vulnerability by correcting how the Windows GDI component handles objects in memory.
(CVE-2020-0885)

- An elevation of privilege vulnerability exists when Windows Error Reporting improperly handles memory.
(CVE-2020-0772)

- An elevation of privilege vulnerability exists when the Windows Universal Plug and Play (UPnP) service improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2020-0781, CVE-2020-0783)

- An elevation of privilege vulnerability exists when Windows improperly handles hard links. An attacker who successfully exploited this vulnerability could overwrite a targeted file leading to an elevated status.
(CVE-2020-0849)

- A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. 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-2020-0832, CVE-2020-0833)

- A remote code execution vulnerability exists in the way the scripting engine handles objects in memory in Microsoft browsers. 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-2020-0768, CVE-2020-0830)

- An elevation of privilege vulnerability exists in the Windows Installer when MSI packages process symbolic links. An attacker who successfully exploited this vulnerability could bypass access restrictions to add or remove files. (CVE-2020-0779)

- An elevation of privilege vulnerability exists when the Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could run processes in an elevated context. (CVE-2020-0791)

- 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-2020-0847)

- An elevation of privilege vulnerability exists when the Windows CSC Service improperly handles memory.
(CVE-2020-0769, CVE-2020-0771)

- An information disclosure vulnerability exists in Windows when the Windows Imaging Component fails to properly handle objects in memory. An attacker who succesfully exploited this vulnerability could obtain information to further compromise the user's system.
There are multiple ways an attacker could exploit this vulnerability: (CVE-2020-0853)

- An elevation of privilege vulnerability exists when the Windows Language Pack Installer improperly handles file operations. An attacker who successfully exploited this vulnerability could run processes in an elevated context. An attacker could exploit this vulnerability by running a specially crafted application on the victim system. The update addresses the vulnerability by correcting the way the Windows Language Pack Installer handles file operations. (CVE-2020-0822)

- An elevation of privilege vulnerability exists when the Windows ActiveX Installer Service improperly handles memory. (CVE-2020-0770, CVE-2020-0773, CVE-2020-0860)
