Summary

Graphics Device Interface (aka GDI or GDI+) in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold and R2; Windows RT 8.1; and Windows 10 Gold, 1511, and 1607 allows remote attackers to execute arbitrary code via a crafted web site, aka "Windows Graphics Component RCE Vulnerability."

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Embedding Scripts within Scripts
    An attack of this type exploits a programs' vulnerabilities that are brought on by allowing remote hosts to execute scripts. The attacker leverages this capability to execute scripts to execute his/her own script by embedding it within other scripts that the target software is likely to execute. The attacker must have the ability to inject script into script that is likely to be executed. If this is done, then the attacker can potentially launch a variety of probes and attacks against the web server's local environment, in many cases the so-called DMZ, back end resources the web server can communicate with, and other hosts. With the proliferation of intermediaries, such as Web App Firewalls, network devices, and even printers having JVMs and Web servers, there are many locales where an attacker can inject malicious scripts. Since this attack pattern defines scripts within scripts, there are likely privileges to execute said attack on the host. Of course, these attacks are not solely limited to the server side, client side scripts like Ajax and client side JavaScript can contain malicious scripts as well. In general all that is required is for there to be sufficient privileges to execute a script, but not protected against writing.
  • Signature Spoofing by Key Theft
    An attacker obtains an authoritative or reputable signer's private signature key by theft and then uses this key to forge signatures from the original signer to mislead a victim into performing actions that benefit the attacker.

descriptionThe remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities : - Multiple information disclosure vulnerabilities exist in the Windows GDI component due to improper handling of objects in memory. A local attacker can exploit these vulnerabilities, via a specially crafted application, to predict memory offsets in a call stack and bypass the Address Space Layout Randomization (ASLR) feature, resulting in the disclosure of memory contents. (CVE-2016-3209, CVE-2016-3262, CVE-2016-3263) - An elevation of privilege vulnerability exists in the Windows kernel due to improper handling of objects in memory. A local attacker can exploit this to elevate privileges and execute code in kernel mode. (CVE-2016-3270) - A remote code execution vulnerability exists in the Windows GDI component due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this vulnerability by convincing a user to visit a specially crafted website or open a specially crafted file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2016-3393) - A remote code execution vulnerability exists in the Windows font library due to improper handling of embedded fonts. An unauthenticated, remote attacker can exploit this vulnerability by convincing a user to visit a specially crafted website or open a specially crafted document file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2016-3396) - An elevation of privilege vulnerability exists in the Windows GDI component due to improper handling of objects in memory. A local attacker can exploit this to elevate privileges and execute code in kernel mode. (CVE-2016-7182)
