Synopsis

The remote Windows host is affected by multiple vulnerabilities.

Description

The remote Windows host is missing security update 4034668. It is, therefore, affected by multiple vulnerabilities :

 - 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.
 (CVE-2017-8620)

 - An elevation of privilege vulnerability exists when the Windows Common Log File System (CLFS) driver improperly handles objects in memory. (CVE-2017-8624)

 - 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, CVE-2017-8641)

 - 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)

 - A security feature bypass vulnerability exists when Internet Explorer fails to validate User Mode Code Integrity (UMCI) policies. The vulnerability could allow an attacker to bypass Device Guard UMCI policies.
 (CVE-2017-8625)

 - 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)

 - 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)

 - 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 control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. (CVE-2017-0250)

 - 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.
 (CVE-2017-8669)

 - 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-2017-8633)

 - 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)

 - 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 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. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Microsoft browsers and then convince a user to view the website. An attacker could also embed an ActiveX control marked "safe for initialization" in an application or Microsoft Office document that hosts the related rendering engine.
 The attacker could also take advantage of compromised websites, and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit the vulnerability. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. (CVE-2017-8636, CVE-2017-8640, CVE-2017-8655, CVE-2017-8672)

 - 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. If the current user is logged on with administrative user rights, an attacker 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-2017-0293)

 - An information disclosure vulnerability exists when Microsoft Edge improperly handles objects in memory. An attacker who successfully exploited the vulnerability could obtain information to further compromise the users system. (CVE-2017-8644, CVE-2017-8652)
