Heap-based buffer overflow in the create_url_list function in gena/gena_device.c in Portable UPnP SDK (aka libupnp) before 1.6.21 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a valid URI followed by an invalid one in the CALLBACK header of an SUBSCRIBE request.

Security readout for executives and security teams

CVE-2016-8863 is a memory corruption flaw in Portable UPnP SDK, also called libupnp. A remote request can crash an affected service and may allow code execution. Business urgency is highest where old libupnp is present in network-reachable software, appliances, or embedded systems. Exposure is most likely in products or services using Portable UPnP SDK/libupnp before 1.6.21 and accepting UPnP GENA SUBSCRIBE traffic. The source bundle does not enumerate downstream products, CPEs, or internet-exposed deployments. Treat this as a high-priority legacy exposure issue. Prioritize internet-reachable, partner-reachable, or unauthenticated network services first, then embedded and appliance inventory where libupnp may be hidden inside vendor firmware. Mitigation focus: Upgrade libupnp or vendor packages to a fixed version, at least 1.6.21 where applicable.; Apply Debian, Gentoo, or product-vendor security updates for affected packages.; Restrict UPnP/GENA access to trusted local networks only..
