Technical details

An out-of-bounds read vulnerability in PowerPoint's file processing logic allows memory disclosure when a user opens a specially crafted presentation file. The vulnerability requires user interaction (opening a file) but can be delivered over the network; exploitation results in information disclosure of process memory contents. No code execution or denial of service is possible through this vector.
