What it is

⚠️ A long TFTP error packet is all it takes for this stack-based overflow to wreak havoc! Think of it like a restaurant that serves portions so big they spill over the plates — if the kitchen isn’t careful, it can create a mess that interrupts service entirely! An attacker can send a crafted error packet that not only causes a denial of service but might even lead to executing arbitrary code. This could disrupt operations and allow unauthorized actions on the affected system — definitely not a good recipe for security!
