Summary
miniupnpc through 2.3.3 Heap Out-of-Bounds Read via minixml parseatt
Details

miniupnpc through 2.3.3 contains a one-byte heap out-of-bounds read vulnerability in the minixml parseatt function that allows malicious UPnP gateways to read past buffer bounds via crafted replies. Attackers on the local network can spoof a gateway serving device descriptions or SOAP responses ending in '=' to crash the client.
