||An issue was discovered in certain Apple products. macOS before 10.12.4 is affected. The issue involves the "AppleGraphicsPowerManagement" component. A race condition allows attackers to execute arbitrary code in a privileged context via a crafted app.

Leveraging Race Conditions
This attack targets a race condition occurring when multiple processes access and manipulate the same resource concurrently and the outcome of the execution depends on the particular order in which the access takes place. The attacker can leverage a race condition by "running the race", modifying the resource and modifying the normal execution flow. For instance a race condition can occur while accessing a file, the attacker can trick the system by replacing the original file with his version and cause the system to read the malicious file.
Leveraging Time-of-Check and Time-of-Use (TOCTOU) Race Conditions
This attack targets a race condition occurring between the time of check (state) for a resource and the time of use of a resource. The typical example is the file access. The attacker can leverage a file access race condition by "running the race", meaning that he would modify the resource between the first time the target program accesses the file and the time the target program uses the file. During that period of time, the attacker could do something such as replace the file and cause an escalation of privilege.

|description||The remote host is running a version of macOS that is 10.12.x prior to 10.12.4. It is, therefore, affected by multiple vulnerabilities in multiple components, some of which are remote code execution vulnerabilities. An unauthenticated, remote attacker can exploit these remote code execution vulnerabilities by convincing a user to visit a specially crafted website, resulting in the execution of arbitrary code in the context of the current user. The affected components are as follows :
- Intel Graphics Driver
- MCX Client
- System Integrity Protection
- WebKit |
