An elevation of privilege vulnerability exists when Windows improperly handles calls to Win32k.sys, aka "Windows Win32k Elevation of Privilege Vulnerability." This affects Windows Server 2008, Windows 7, Windows Server 2008 R2.

The remote Windows host is missing security update 4467700 or cumulative update 4467706. 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 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 elevation of privilege vulnerability exists when     Windows improperly handles calls to Win32k.sys. An     attacker who successfully exploited this vulnerability     could run arbitrary code in the security context of the     local system. An attacker could then install programs;
    view, change, or delete data; or create new accounts     with full user rights.  (CVE-2018-8589)

  - 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)

  - 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)

  - 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     &quot;Kernel Remote Procedure Call Provider&quot; driver     improperly initializes objects in memory.
    (CVE-2018-8407)

  - 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)

The remote Windows host is missing security update 4467106 or cumulative update 4467107. 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.

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 remote code execution vulnerability exists when     Internet Explorer improperly accesses 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-2018-8570)

  - 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.
