Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Leveraging/Manipulating Configuration File Search Paths This attack loads a malicious resource into a program's standard path used to bootstrap and/or provide contextual information for a program like a path variable or classpath. J2EE applications and other component based applications that are built from multiple binaries can have very long list of dependencies to execute. If one of these libraries and/or references is controllable by the attacker then application controls can be circumvented by the attacker. A standard UNIX path looks similar to this If the attacker modifies the path variable to point to a locale that includes malicious resources then the user unwittingly can execute commands on the attackers' behalf: This is a form of usurping control of the program and the attack can be done on the classpath, database resources, or any other resources built from compound parts. At runtime detection and blocking of this attack is nearly impossible, because the configuration allows execution.

| 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.
