Portable SDK for UPnP Devices Contains Buffer Overflow Vulnerabilities

The Portable Software Developer Kit (SDK) for Universal Plug-n-Play (UPnP) Devices contains a libupnp library, originally known as the Intel SDK for UPnP Devices, which is vulnerable to multiple stack-based buffer overflows when handling malicious Simple Service Discovery Protocol (SSDP) requests. This library is used in several vendor network devices, in addition to media streaming and file sharing applications.
