and OZS products, which can be exploited by malicious people to
compromise a vulnerable device.

libupnp.

For more information:

2) Multiple boundary errors within the "unique_service_name()"
function (ssdp/ssdp_ctrlpt.c) in libupnp when handling SSDP requests
can be exploited to cause stack-based buffer overflows.
