    Summary: ntop nDPI before 6.0 Heap Buffer Overflow via ndpi_json_string_escape

    Details: ntop nDPI versions before 6.0 contain a heap buffer overflow vulnerability in the ndpi_json_string_escape function that writes beyond caller-supplied buffer boundaries. Attackers can trigger the overflow by supplying crafted network packet data including TLS SNI, HTTP headers, or DNS names that reach the vulnerable function, causing heap corruption.
