What it is

🚨 A crafty image file could trigger a buffer overflow in your Apple device! This vulnerability can lead to arbitrary code execution, and it's actively exploited! 🔥 Think of it like a crowded elevator that suddenly jams; too many people (data) trying to fit in can cause it to malfunction and let anyone in, even those who shouldn’t be there. If exploited, an attacker could gain full control of your device, allowing them to run malicious code, steal personal data, or even hijack sensitive information. This is absolutely devastating, especially since Apple has confirmed it's being actively exploited.
