Description

Stack-based buffer overflow in the unique_service_name function in ssdp/ssdp_server.c in the SSDP parser in the portable SDK for UPnP Devices (aka libupnp, formerly the Intel SDK for UPnP devices) before 1.6.18 allows remote attackers to execute arbitrary code via a UDP packet with a crafted string that is not properly handled after a certain pointer subtraction.
