A remote code execution vulnerability exists in the way that the Chakra scripting engine handles objects in memory in Microsoft Edge, aka "Chakra Scripting Engine Memory Corruption Vulnerability." This affects Microsoft Edge, ChakraCore. This CVE ID is unique from CVE-2018-8541, CVE-2018-8542, CVE-2018-8543, CVE-2018-8555, CVE-2018-8556, CVE-2018-8557, CVE-2018-8588.

The remote Windows host is missing security update 4467708.
It is, therefore, affected by multiple vulnerabilities :

  - A security feature bypass vulnerability exists in     Microsoft JScript that could allow an attacker to bypass     Device Guard.  (CVE-2018-8417)

  - 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)

  - 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.

    (CVE-2018-8485, CVE-2018-8554, CVE-2018-8561)

  - 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 in the     way that Microsoft Edge handles cross-origin requests.
    An attacker who successfully exploited this     vulnerability could determine the origin of all webpages     in the affected browser.  (CVE-2018-8545)

    (CVE-2018-8476)

  - An elevation of privilege vulnerability exists in     Windows 10 version 1809 when installed from physical     media (USB, DVD, etc.) with the keep nothing option     selected during installation. Successful exploitation of     the vulnerability could allow an attacker to gain local     access to an affected system.  (CVE-2018-8592)

  - 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 vulnerability exists when     Windows improperly handles calls to Advanced Local     Procedure Call (ALPC).

    (CVE-2018-8584)

  - 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     Windows Audio Service fails to properly handle objects     in memory. An attacker who successfully exploited the     vulnerability could potentially disclose memory contents     of a elevated process.  (CVE-2018-8454)

  - A spoofing vulnerability exists when Microsoft Edge     improperly handles specific HTML content. 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-2018-8564)

  - 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)

An attacker who successfully exploited the     vulnerability could gain the same user rights as the     current user.  (CVE-2018-8541, CVE-2018-8542,     CVE-2018-8543, CVE-2018-8551, CVE-2018-8555,     CVE-2018-8556, CVE-2018-8557, CVE-2018-8588)
