Synopsis
The remote Windows host is affected by multiple vulnerabilities.Description
The remote Windows host is missing security update 4493467 or cumulative update 4493446. It is, therefore, affected by multiple vulnerabilities :- A security feature bypass vulnerability exists in Windows which could allow an attacker to bypass Device Guard when Windows improperly handles calls to the LUAFV driver (luafv.sys). An attacker who successfully exploited this vulnerability could circumvent a User Mode Code Integrity (UMCI) policy on the machine.
(CVE-2019-0732)
- An information disclosure vulnerability exists when the Terminal Services component improperly discloses the contents of its memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise a users system. (CVE-2019-0839)
- 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-2019-0842)
- A remote code execution vulnerability exists when Windows improperly handles objects in memory. An attacker who successfully exploited these vulnerabilities could take control of an affected system. (CVE-2019-0856)
- An information disclosure vulnerability exists when the Windows TCP/IP stack improperly handles fragmented IP packets. An attacker who successfully exploited this vulnerability could obtain information to further compromise the users system. (CVE-2019-0688)
- A remote code execution vulnerability exists when the Microsoft XML Core Services MSXML parser processes user input. An attacker who successfully exploited the vulnerability could run malicious code remotely to take control of the users system. (CVE-2019-0790, CVE-2019-0791, CVE-2019-0792, CVE-2019-0793, CVE-2019-0795)
- 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-2019-0803, CVE-2019-0859)
- 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-2019-0752, CVE-2019-0753, CVE-2019-0862)
- 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-2019-0846, CVE-2019-0847, CVE-2019-0851, CVE-2019-0877, CVE-2019-0879)
- An elevation of privilege vulnerability exists when Windows improperly handles calls to the LUAFV driver (luafv.sys). 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-2019-0730, CVE-2019-0731, CVE-2019-0805, CVE-2019-0836)
- 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-2019-0802, CVE-2019-0849)
- An information disclosure vulnerability exists when Windows Task Scheduler improperly discloses credentials to Windows Credential Manager. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2019-0838)
- An information disclosure vulnerability exists when the scripting engine does not properly handle objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2019-0835)
- An elevation of privilege vulnerability exists when Windows improperly handles calls to the LUAFV driver (luafv.sys). An attacker who successfully exploited this vulnerability could set the short name of a file with a long name to an arbitrary short name, overriding the file system with limited privileges. (CVE-2019-0796)
- 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-2019-0848)
- 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-2019-0844)
- An elevation of privilege vulnerability exists when the Windows Client Server Run-Time Subsystem (CSRSS) fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code. An attacker could then install programs;
view, change, or delete data; or create new accounts with full user rights. (CVE-2019-0735)
- A remote code execution vulnerability exists when OLE automation improperly handles objects in memory. An attacker who successfully exploited the vulnerability could gain execution on the victim system.
(CVE-2019-0794)
- A remote code execution vulnerability exists when the IOleCvt interface renders ASP webpage content. An attacker who successfully exploited the vulnerability could run malicious code remotely to take control of the users system. (CVE-2019-0845)
- A tampering vulnerability exists when Microsoft browsers do not properly validate input under specific conditions. An attacker who exploited the vulnerability could pass custom command line parameters.
(CVE-2019-0764)
- 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-2019-0853)
