Summary

An issue was discovered in certain Apple products. macOS before 10.13.2 is affected. The issue involves the "Intel Graphics Driver" component. It allows attackers to execute arbitrary code in a privileged context or cause a denial of service (out-of-bounds read) via a crafted app.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • Overread Buffers
    An adversary attacks a target by providing input that causes an application to read beyond the boundary of a defined buffer. This typically occurs when a value influencing where to start or stop reading is set to reflect positions outside of the valid memory location of the buffer. This type of attack may result in exposure of sensitive information, a system crash, or arbitrary code execution.

descriptionAppleIntelCapriController::GetLinkConfig trusts a user-supplied value in the structure input which it uses to index a small table of pointers without bounds checking. The OOB-read pointer is passed to AppleIntelFramebuffer::validateDisplayMode which will read a pointer to a C++ object from that buffer (at offset 2138h) and call a virtual method allowing trivial kernel code execution.
