Description A buffer overflow occurs when the device accepts and stores excessively long hostnames from LAN hosts without proper length validation. The affected code performs unchecked copies and concatenations into fixed-size buffers. A crafted long hostname can overflow the buffer, causing a denial-of-service (DoS) condition and potentially enabling remote code execution.
