Synopsis
The remote Windows host is affected by multiple vulnerabilities.Description
The remote Windows host is missing security update 4550965 or cumulative update 4550964. It is, therefore, affected by multiple vulnerabilities :- 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-2020-0962)
- 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-2020-0968)
- 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-2020-0889, CVE-2020-0953, CVE-2020-0959, CVE-2020-0960, CVE-2020-0988, CVE-2020-0992, CVE-2020-0994, CVE-2020-0995, CVE-2020-0999, CVE-2020-1008)
- A remoted code execution vulnerability exists in the way that Microsoft Windows Codecs Library handles objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code. Exploitation of the vulnerability requires that a program process a specially crafted image file. The update addresses the vulnerability by correcting how Microsoft Windows Codecs Library handles objects in memory. (CVE-2020-0965)
- An elevation of privilege vulnerability exists in the way that the Microsoft Store Install Service handles file operations in protected locations. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-1009)
- A remote code execution vulnerability exists in Microsoft Windows when the Windows Adobe Type Manager Library improperly handles a specially-crafted multi- master font - Adobe Type 1 PostScript format. 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, such as convincing a user to open a specially crafted document or viewing it in the Windows Preview pane. The update addresses the vulnerability by correcting how the Windows Adobe Type Manager Library handles Type1 fonts. (CVE-2020-0938, CVE-2020-1020)
- An information disclosure vulnerability exists when Media Foundation improperly handles objects in memory.
An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2020-0946)
- An elevation of privilege vulnerability exists in the way that the Windows Kernel handles objects in memory.
An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
(CVE-2020-1027)
- 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-2020-0821, CVE-2020-1007)
- An elevation of privilege vulnerability exists when the Windows kernel 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-2020-1000)
- 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-2020-0687)
- 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-2020-0964)
- An elevation of privilege vulnerability exists when the Windows Work Folder 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 update addresses the vulnerability by correcting the way the Windows Work Folder Service handles file operations. (CVE-2020-1094)
- An elevation of privilege vulnerability exists in the Microsoft Windows Update Client when it does not properly handle privileges. 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-2020-1014)
- 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-2020-0907)
- 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-2020-1004)
- An elevation of privilege vulnerability exists in the way that the User-Mode Power Service (UMPS) handles objects in memory. An attacker who successfully exploited the vulnerability could execute code with elevated permissions. (CVE-2020-1015)
- An information disclosure vulnerability exists when the Microsoft Windows Graphics Component improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2020-0982, CVE-2020-0987, CVE-2020-1005)
- An elevation of privilege vulnerability exists in Windows when the Windows kernel-mode driver 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-2020-0956, CVE-2020-0957, CVE-2020-0958)
- 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-2020-0895, CVE-2020-0966, CVE-2020-0967)
- 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-2020-0952)
- A denial of service vulnerability exists in Windows DNS when it fails to properly handle queries. An attacker who successfully exploited this vulnerability could cause the DNS service to become nonresponsive.
(CVE-2020-0993)
- An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory. An attacker who successfully exploited the vulnerability could read privileged data across trust boundaries. (CVE-2020-0955)
