high Nessus Plugin ID 102270
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4034672 or cumulative update 4034681. It is, therefore, affected by multiple vulnerabilities :

- A denial of service vulnerability exists when Microsoft Windows improperly handles NetBIOS packets. An attacker who successfully exploited this vulnerability could cause a target computer to become completely unresponsive. A remote unauthenticated attacker could exploit this vulnerability by sending a series of TCP packets to a target system, resulting in a permanent denial of service condition. The update addresses the vulnerability by correcting how the Windows network stack handles NetBIOS traffic. (CVE-2017-0174)

- A buffer overflow vulnerability exists in the Microsoft JET Database Engine that could allow remote code execution on an affected system. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
(CVE-2017-0250)

- A remote code execution vulnerability exists when Microsoft Windows PDF Library improperly handles objects in memory. The vulnerability could corrupt memory in a way that enables an attacker to 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-2017-0293)

- A remote code execution vulnerability exists in Windows Input Method Editor (IME) when IME improperly handles parameters in a method of a DCOM class. The DCOM server is a Windows component installed regardless of which languages/IMEs are enabled. An attacker can instantiate the DCOM class and exploit the system even if IME is not enabled. (CVE-2017-8591)

- 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-2017-8593)

- A remote code execution vulnerability exists when Windows Search 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.To exploit the vulnerability, the attacker could send specially crafted messages to the Windows Search service. An attacker with access to a target computer could exploit this vulnerability to elevate privileges and take control of the computer. Additionally, in an enterprise scenario, a remote unauthenticated attacker could remotely trigger the vulnerability through an SMB connection and then take control of a target computer.The security update addresses the vulnerability by correcting how Windows Search handles objects in memory. (CVE-2017-8620)

- An elevation of privilege vulnerability exists when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. (CLFS) is a high-performance, general-purpose log file subsystem that dedicated client applications can use and multiple clients can share to optimize log access. (CVE-2017-8624)

- This security update resolves a vulnerability in Windows Error Reporting (WER). The vulnerability could allow elevation of privilege if successfully exploited by an attacker. An attacker who successfully exploited this vulnerability could gain greater access to sensitive information and system functionality. This update corrects the way the WER handles and executes files.
(CVE-2017-8633)

- A remote code execution vulnerability exists in the way JavaScript engines render when handling 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-2017-8635)

- A remote code execution vulnerability exists in the way that Microsoft browser JavaScript engines render content when handling 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. (CVE-2017-8636)

- A remote code execution vulnerability exists in the way JavaScript engines render when handling 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-2017-8641)

- A remote code execution vulnerability exists when Microsoft browsers improperly access objects in memory.
The vulnerability could corrupt memory in such a way that enables an attacker to 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-2017-8653)

- A remote code execution vulnerability exists when Windows Hyper-V on a host server fails to properly validate input from an authenticated user on a guest operating system. (CVE-2017-8664)

- 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-2017-8666)

- An information disclosure vulnerability exists when the Volume Manager Extension Driver component improperly provides kernel information. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system.To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.The security update addresses the vulnerability by correcting how Volume Manager Extension Driver handles objects in memory. (CVE-2017-8668)

- A remote code execution vulnerability exists in the way Microsoft browsers handle objects in memory while rendering content. 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. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system.
An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. (CVE-2017-8669)
