Description
Realtek Jungle SDK version v2.x up to v3.4.14B provides a 'WiFi Simple Config' server that implements both UPnP and SSDP protocols. The binary is usually named wscd or mini_upnpd and is the successor to miniigd. The server is vulnerable to a heap buffer overflow that is present due to unsafe crafting of SSDP NOTIFY messages from received M-SEARCH messages ST header.
