KB4486993: Windows Server 2012 February 2019 Security Update

critical Nessus Plugin ID 122125

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4486993 or cumulative update 4487025. It is, therefore, affected by multiple vulnerabilities :

- A remote code execution vulnerability exists in .NET Framework and Visual Studio software when the software fails to check the source markup of a file. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker 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-2019-0613)

- 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-2019-0623)

- 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-2019-0635)

- 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-2019-0602, CVE-2019-0615, CVE-2019-0616, CVE-2019-0619, CVE-2019-0660, CVE-2019-0664)

- 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. An authenticated attacker could exploit this vulnerability by running a specially crafted application. The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory. (CVE-2019-0661)

- An information disclosure vulnerability exists when the Human Interface Devices (HID) component improperly handles objects in memory. An attacker who successfully exploited this vulnerability could obtain information to further compromise the victims system. (CVE-2019-0600, CVE-2019-0601)

- 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-2019-0621)

- 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-2019-0628)

- An information disclosure vulnerability exists when Internet Explorer improperly handles objects in memory.
An attacker who successfully exploited this vulnerability could test for the presence of files on disk. For an attack to be successful, an attacker must persuade a user to open a malicious website. The security update addresses the vulnerability by changing the way Internet Explorer handles objects in memory.
(CVE-2019-0676)

- A vulnerability exists in certain .Net Framework API's and Visual Studio in the way they parse URL's. An attacker who successfully exploited this vulnerability could use it to bypass security logic intended to ensure that a user-provided URL belonged to a specific hostname or a subdomain of that hostname. This could be used to cause privileged communication to be made to an untrusted service as if it was a trusted service.
(CVE-2019-0657)

- 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-2019-0618, CVE-2019-0662)

- An information vulnerability exists when Windows improperly discloses file information. Successful exploitation of the vulnerability could allow the attacker to read the contents of files on disk.
(CVE-2019-0636)

- A spoofing vulnerability exists when Microsoft browsers improperly handles specific redirects. An attacker who successfully exploited this vulnerability could trick a user into believing that the user was on a legitimate website. The specially crafted website could either spoof content or serve as a pivot to chain an attack with other vulnerabilities in web services.
(CVE-2019-0654)

- A remote code execution vulnerability exists in the way that the Microsoft Server Message Block 2.0 (SMBv2) server handles certain requests. An attacker who successfully exploited the vulnerability could gain the ability to execute code on the target server.
(CVE-2019-0630, CVE-2019-0633)

- A memory corruption vulnerability exists in the Windows Server DHCP service when an attacker sends specially crafted packets to a DHCP server. An attacker who successfully exploited the vulnerability could run arbitrary code on the DHCP server. (CVE-2019-0626)

- 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-2019-0595, CVE-2019-0596, CVE-2019-0597, CVE-2019-0598, CVE-2019-0599, CVE-2019-0625)

- An information disclosure vulnerability exists when the Windows kernel improperly initializes objects in memory.
To exploit this vulnerability, an authenticated attacker could run a specially crafted application. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user's system.
(CVE-2019-0663)
