In short

A flaw in how Apple devices process audio in media files allows attackers to run malicious code by crafting a specially designed file. This is critical because it can be exploited remotely without user interaction beyond opening the file.

Technical detail

A buffer overflow vulnerability (CWE-119) in audio stream processing allows arbitrary code execution when a maliciously crafted media file is processed. The attack requires no user interaction beyond file processing, and Apple confirms active exploitation against targeted iOS users on unpatched versions.
