Microsoft GDI Component in Windows 7 SP1 and Windows Server 2008 SP2 and R2 SP1 allows an attacker to log on to an affected system and run a specially crafted application to compromise the user's system, due improperly disclosing kernel memory addresses, aka "Windows GDI Information Disclosure Vulnerability".

The remote Windows host is missing multiple security updates released on 2017/11/14. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists when the     Windows kernel improperly initializes objects in memory.
    (CVE-2017-11880)   
  - An information disclosure vulnerability exists in the     way that the Microsoft Windows Embedded OpenType (EOT)     font engine parses specially crafted embedded fonts. An     attacker who successfully exploited this vulnerability     could potentially read data that was not intended to be     disclosed. Note that this vulnerability would not allow     an attacker to execute code or to elevate their user     rights directly, but it could be used to obtain     information that could be used to try to further     compromise the affected system.  (CVE-2017-11832,     CVE-2017-11835)   
  - An elevation of privilege vulnerability exists when the     Windows kernel 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-2017-11847)   
  - An information disclosure vulnerability exists when the     Windows kernel fails to properly initialize a memory     address. An attacker who successfully exploited this     vulnerability could obtain information to further     compromise the users system.  (CVE-2017-11831,     CVE-2017-11849, CVE-2017-11853)   
  - A denial of service vulnerability exists when Windows     Search improperly handles objects in memory. An attacker     who successfully exploited the vulnerability could cause     a remote denial of service against a system.
    (CVE-2017-11788)   
  - A Win32k information disclosure vulnerability exists     when the Windows GDI component improperly discloses     kernel memory addresses. An attacker who successfully     exploited the vulnerability could obtain information to     further compromise the users system.  (CVE-2017-11851,     CVE-2017-11852)

The remote Windows host is missing security update 4048960 or cumulative update 4048957. It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists in the way     that Microsoft browsers access objects in memory. The     vulnerability could corrupt memory in a way that could     allow 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-2017-11827,     CVE-2017-11858)

  - A remote code execution vulnerability exists in the way     the scripting engine handles 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-2017-11837, CVE-2017-11838, CVE-2017-11843,     CVE-2017-11846)

  - 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-2017-11855,     CVE-2017-11856, CVE-2017-11869)

  - An information vulnerability exists when Windows Media     Player improperly discloses file information. Successful     exploitation of the vulnerability could allow the     attacker to test for the presence of files on disk.
    (CVE-2017-11768)

  - An information disclosure vulnerability exists when the     scripting engine does not properly handle objects in     memory in Internet Explorer. An attacker who     successfully exploited the vulnerability could obtain     information to further compromise the users system.
    (CVE-2017-11834)

  - An information disclosure vulnerability exists when the     Windows kernel improperly initializes objects in memory.
    (CVE-2017-11880)

  - An information disclosure vulnerability exists in the     way that the Microsoft Windows Embedded OpenType (EOT)     font engine parses specially crafted embedded fonts. An     attacker who successfully exploited this vulnerability     could potentially read data that was not intended to be     disclosed. Note that this vulnerability would not allow     an attacker to execute code or to elevate their user     rights directly, but it could be used to obtain     information that could be used to try to further     compromise the affected system.

  - An information disclosure vulnerability exists when the     scripting engine does not properly handle objects in     memory in Microsoft browsers. An attacker who     successfully exploited the vulnerability could obtain     information to further compromise the users system.
    (CVE-2017-11791)

  - An elevation of privilege vulnerability exists when the     Windows kernel 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-2017-11847)

  - An information disclosure vulnerability exists when the     Windows kernel fails to properly initialize a memory     address.

  - An information disclosure vulnerability exists when     Internet Explorer improperly handles page content, which     could allow an attacker to detect the navigation of the     user leaving a maliciously crafted page.
    (CVE-2017-11848)

  - A denial of service vulnerability exists when Windows     Search improperly handles objects in memory. An attacker     who successfully exploited the vulnerability could cause     a remote denial of service against a system.
