Synopsis
The remote Windows host is affected by multiple vulnerabilities.Description
The remote Windows host is missing security update 4467703 or cumulative update 4467697. It is, therefore, affected by multiple vulnerabilities :- 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-2018-8552)
- 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-2018-8450)
- A remote code execution vulnerability exists when PowerShell improperly handles specially crafted files.
An attacker who successfully exploited this vulnerability could execute malicious code on a vulnerable system. (CVE-2018-8256)
- A security feature bypass exists when Windows incorrectly validates kernel driver signatures. An attacker who successfully exploited this vulnerability could bypass security features and load improperly signed drivers into the kernel. In an attack scenario, an attacker could bypass security features intended to prevent improperly signed drivers from being loaded by the kernel. The update addresses the vulnerability by correcting how Windows validates kernel driver signatures. (CVE-2018-8549)
- An information disclosure vulnerability exists when DirectX 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 DirectX handles objects in memory.
(CVE-2018-8563)
- A tampering vulnerability exists in PowerShell that could allow an attacker to execute unlogged code.
(CVE-2018-8415)
- A remote code execution vulnerability exists in the way that Windows Deployment Services TFTP Server handles objects in memory. An attacker who successfully exploited the vulnerability could execute arbitrary code with elevated permissions on a target system.
(CVE-2018-8476)
- 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-2018-8565)
- 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-2018-8544)
- An elevation of privilege exists in Windows COM Aggregate Marshaler. An attacker who successfully exploited the vulnerability could run arbitrary code with elevated privileges. (CVE-2018-8550)
- An information disclosure vulnerability exists when the Windows kernel improperly initializes objects in memory.
(CVE-2018-8408)
- A cross-site-scripting (XSS) vulnerability exists when an open source customization for Microsoft Active Directory Federation Services (AD FS) does not properly sanitize a specially crafted web request to an affected AD FS server. An authenticated attacker could exploit the vulnerability by sending a specially crafted request to an affected AD FS server. The attacker who successfully exploited the vulnerability could then perform cross-site scripting attacks on affected systems and run scripts in the security context of the current user. The attacks could allow the attacker to read content that the attacker is not authorized to read, use the victim's identity to take actions on the AD FS site on behalf of the user, such as change permissions and delete content, and inject malicious content in the browser of the user. The security update addresses the vulnerability by helping to ensure that the open source customization for AD FS properly sanitizes web requests.
(CVE-2018-8547)
- 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-2018-8553)
- An information disclosure vulnerability exists when "Kernel Remote Procedure Call Provider" driver improperly initializes objects in memory.
(CVE-2018-8407)
- 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-2018-8562)
- An elevation of privilege vulnerability exists when DirectX improperly handles 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-2018-8485, CVE-2018-8561)
