pupnp: pupnp is an SDK for development of UPnP device and control point applications
CVE-2026-77630 is fixed in pupnp on 1 platform by DEBIAN-CVE-2026-77630 (version 1:22.1.8-2), released October 21, 2026. It is not reported as exploited. Patch Radar priority: High.
pupnp is an SDK for development of UPnP device and control point applications. Prior to 22.0.4, parse_hostport in upnp/src/genlib/net/uri/uri.c synchronously calls getaddrinfo while parse_uri is processing attacker-supplied hostnames from inbound HTTP request targets in upnp/src/genlib/net/http/httpparser.c and GENA SUBSCRIBE CALLBACK headers handled by create_url_list in upnp/src/gena/gena_device.c. A remote unauthenticated peer can choose a slow or nonresponsive hostname and block a bounded miniserver worker for the resolver timeout, allowing a small number of requests to exhaust the thread pool and deny UPnP service. This issue is fixed in 22.0.4.
