⚠️ A heap-based buffer over-read in the nDPI OpenVPN dissector could lead to unexpected behavior—think of it as a waiter retrieving your order without checking it first! 🍽️ Imagine a restaurant where the chef grabs ingredients without reading the order ticket. If they misjudge the quantity or type, you might end up with a dish that’s not only wrong but potentially harmful! If exploited, this vulnerability could lead to data leakage or crashes while processing OpenVPN packets, potentially exposing sensitive information or disrupting your network traffic. While it's not actively exploited, it's still crucial to keep an eye out for unusual behavior!
