The Graphics component in the kernel in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; and Windows 7 SP1 allows local users to gain privileges via a crafted application, aka "Windows Graphics Elevation of Privilege Vulnerability."

The remote Windows host is missing a security update KB4015195. It is, therefore, affected by multiple vulnerabilities:

  - An information disclosure vulnerability in the win32k     component due to improper handling of kernel     information. A local attacker can exploit this, via a     specially crafted application,to disclose sensitive     information. (CVE-2017-0058)

  - 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. (CVE-2017-0155)

The remote Windows host is missing security update 4015546 or cumulative update 4015549. It is, therefore, affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists in the     open-source libjpeg image processing library due to     improper handling of objects in memory. An     unauthenticated, remote attacker can exploit this to     disclose sensitive information that can be utilized to     bypass ASLR security protections. (CVE-2013-6629)

  - An information disclosure vulnerability exists in the     win32k component due to improper handling of kernel     information. A local attacker can exploit this, via a     specially crafted application, to disclose sensitive     information. (CVE-2017-0058)

  - Multiple privilege escalation vulnerabilities exist in     the Microsoft Graphics Component due to improper     handling of objects in memory. A local attacker can     exploit this, via a specially crafted application, to     execute arbitrary code with elevated privileges.
    (CVE-2017-0155, CVE-2017-0156)

  - A flaw exists in the VBScript engine due to improper     handling of objects in memory. An unauthenticated,     remote attacker can exploit this, by convincing a user     to visit a malicious website or open a specially crafted     document file, to execute arbitrary code.
    (CVE-2017-0158)

  - Multiple flaws exist in Windows Hyper-V Network Switch     due to improper validation of input from the guest     operating system. A local attacker can exploit these,     via a specially crafted application on the guest, to     execute arbitrary code on the host system.
    (CVE-2017-0163, CVE-2017-0180)

  - A flaw exists in LDAP due to buffer request lengths not     being properly calculated. An unauthenticated, remote     attacker can exploit this, via specially crafted traffic     sent to a Domain Controller, to run processes with     elevated privileges. (CVE-2017-0166)

  - An information disclosure vulnerability exists in     Windows Hyper-V Network Switch due to improper validation     of user-supplied input. A guest attacker can exploit     this to disclose sensitive information on the host     server. (CVE-2017-0168)

  - Multiple denial of service vulnerabilities exist in     Windows Hyper-V Network Switch due to improper     validation of input from the guest operating system. A     local attacker on the guest can exploit these     vulnerabilities, via a specially crafted application, to     crash the host system. (CVE-2017-0182, CVE-2017-0183)

  - A denial of service vulnerability exists in Hyper-V due     to improper validation of input from a privileged user     on a guest operating system. A local attacker on the     guest can exploit this, via a specially crafted     application, to cause the host system to crash.
    (CVE-2017-0184)

  - A flaw exists in Windows due to improper handling of     objects in memory that allows an attacker to cause a     denial of service condition. (CVE-2017-0191)

  - An information disclosure vulnerability exists in the     Adobe Type Manager Font Driver (ATMFD.dll) due to     improper handling of objects in memory. An     unauthenticated, remote attacker can exploit this, by     convincing a user to open a specially crafted document     or visit a malicious web page, to disclose sensitive     information. (CVE-2017-0192)

  - An arbitrary code execution vulnerability exists in     Microsoft Office and Windows WordPad due to improper     handling of specially crafted files. An unauthenticated,     remote attacker can exploit this, by convincing a user     to open a malicious file, to execute arbitrary code in     the context of the current user. Note that this     vulnerability is being utilized to spread the Petya     ransomware. (CVE-2017-0199)

  - A memory corruption issue exists in Internet Explorer     due to improper validation of user-supplied input. An     unauthenticated, remote attacker can exploit this, by     convincing a user to visit a malicious website, to     execute arbitrary code. (CVE-2017-0202)

  - A privilege escalation vulnerability exists in Internet     Explorer due to a failure to properly enforce     cross-domain policies. An unauthenticated, remote     attacker can exploit this to inject arbitrary content     and gain elevated privileges. (CVE-2017-0210)
