NONE Summary
The GDI component in Microsoft Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Office for Mac 2011, and Office 2016 for Mac allows remote attackers to obtain sensitive information from process memory via a crafted web site, aka "GDI Information Disclosure Vulnerability."

Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Subverting Environment Variable Values The attacker directly or indirectly modifies environment variables used by or controlling the target software. The attacker's goal is to cause the target software to deviate from its expected operation in a manner that benefits the attacker.
- Footprinting An attacker engages in probing and exploration activity to identify constituents and properties of the target. Footprinting is a general term to describe a variety of information gathering techniques, often used by attackers in preparation for some attack. It consists of using tools to learn as much as possible about the composition, configuration, and security mechanisms of the targeted application, system or network. Information that might be collected during a footprinting effort could include open ports, applications and their versions, network topology, and similar information. While footprinting is not intended to be damaging (although certain activities, such as network scans, can sometimes cause disruptions to vulnerable applications inadvertently) it may often pave the way for more damaging attacks.
- Exploiting Trust in Client (aka Make the Client Invisible) An attack of this type exploits a programs' vulnerabilities in client/server communication channel authentication and data integrity. It leverages the implicit trust a server places in the client, or more importantly, that which the server believes is the client. An attacker executes this type of attack by placing themselves in the communication channel between client and server such that communication directly to the server is possible where the server believes it is communicating only with a valid client. There are numerous variations of this type of attack.
- Browser Fingerprinting An attacker carefully crafts small snippets of Java Script to efficiently detect the type of browser the potential victim is using. Many web-based attacks need prior knowledge of the web browser including the version of browser to ensure successful exploitation of a vulnerability. Having this knowledge allows an attacker to target the victim with attacks that specifically exploit known or zero day weaknesses in the type and version of the browser used by the victim. Automating this process via Java Script as a part of the same delivery system used to exploit the browser is considered more efficient as the attacker can supply a browser fingerprinting method and integrate it with exploit code, all contained in Java Script and in response to the same web page request by the browser.
- Session Credential Falsification through Prediction This attack targets predictable session ID in order to gain privileges. The attacker can predict the session ID used during a transaction to perform spoofing and session hijacking.

NASL family Windows : Microsoft Bulletins NASL id SMB_NT_MS16-146.NASL description The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists in the Windows GDI component due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website or open a specially crafted document file, to disclose the contents of memory. (CVE-2016-7257) - Multiple remote code execution vulnerabilities exist in the Windows Graphics Component due to improper handling of objects in memory. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a specially crafted website or open a specially crafted document file, to execute arbitrary code in the context of the current user. (CVE-2016-7272, CVE-2016-7273) last seen 2020-06-01 modified 2020-06-02 plugin id 95765 published 2016-12-13 reporter This script is Copyright (C) 2016-2018 Tenable Network Security, Inc. source https://www.tenable.com/plugins/nessus/95765 title MS16-146: Security Update for Microsoft Graphics Component (3204066) NASL family MacOS X Local Security Checks NASL id MACOSX_MS16-148_OFFICE.NASL description The Microsoft Office application installed on the remote macOS or Mac OS X host is missing a security update. It is, therefore, affected by multiple vulnerabilities : - An information disclosure vulnerability exists in the Graphics Device Interface (GDI) component due to improper handling of objects in memory. A local attacker can exploit this, via a specially crafted application, to circumvent the Address Space Layout Randomization (ASLR) feature and disclose sensitive memory information. (CVE-2016-7257) - Multiple remote code execution vulnerabilities exist in Microsoft Office software due to a failure to properly handle objects in memory. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted Office file, resulting in the execution of arbitrary code in the context of the current user. (CVE-2016-7263, CVE-2016-7298) - Multiple information disclosure vulnerabilities exist in Microsoft Office software due to an out-of-bounds memory read error. An unauthenticated, remote attacker can exploit these vulnerabilities by convincing a user to open a specially crafted Office file, resulting in the disclosure of memory contents. (CVE-2016-7264, CVE-2016-7268, CVE-2016-7276, CVE-2016-7290, CVE-2016-7291) - An arbitrary command execution vulnerability exists in Microsoft Office due to improper validation of registry settings when running embedded content. An unauthenticated, remote attacker can exploit this by convincing a user to open a specially crafted document file multiple times, resulting in a bypass of security restrictions and the execution of arbitrary commands. (CVE-2016-7266) - An elevation of privilege vulnerability exists in the Microsoft AutoUpdate (MAU) application due to improper validation of updates. A local attacker can exploit this by placing a specially crafted application in a location used by the update application, resulting in the ability to execute arbitrary code in a privileged context.
