CVE-2025-43494

⚡ A mail header parsing flaw could lead to a persistent denial-of-service — imagine your inbox getting jammed with non-stop spam! 📧 Think of this vulnerability like a poorly designed postal system that can't handle certain types of mail; it gets overwhelmed and stops delivering any mail at all. Just like that system, our devices could freeze up and become unusable if they encounter the wrong header. If exploited, an attacker could effectively shut down email functionality, making it impossible to send or receive messages — a frustrating situation that could disrupt both personal communications and business operations. This could lead to significant downtime and hinder productivity.
