⚠️ A single long error message can crash Pegasus Mail! This stack-based buffer overflow opens the door for remote servers to potentially execute arbitrary code, and that’s just plain risky! Think of this vulnerability like an overflowing trash can at a restaurant. If too much waste piles up, it spills over, causing a real mess that disrupts service — just like how this overflow can crash your mail application or worse! If an attacker sends a lengthy error message, they might trigger a denial of service, causing your email client to crash unexpectedly. In the worst-case scenario, they could execute malicious code on your system, leading to data breaches or further exploitation. Talk about a bad mail day!
