{"id":"DEBIAN-CVE-2026-77630","details":"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.","modified":"2026-10-17T05:00:06.741677359Z","published":"2026-10-16T16:21:03.187Z","upstream":["CVE-2026-77630"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-77630"}],"affected":[{"package":{"name":"pupnp","ecosystem":"Debian:13","purl":"pkg:deb/debian/pupnp?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.14.20-1","1:1.14.20-1+deb13u1","1:1.14.23-1","1:1.14.24-1","1:1.14.24-2","1:1.14.24-3","1:1.14.25-1","1:1.14.31-1","1:1.18.0-1","1:1.18.4-1","1:1.18.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-77630.json"}},{"package":{"name":"pupnp","ecosystem":"Debian:14","purl":"pkg:deb/debian/pupnp?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:1.14.20-1","1:1.14.23-1","1:1.14.24-1","1:1.14.24-2","1:1.14.24-3","1:1.14.25-1","1:1.14.31-1","1:1.18.0-1","1:1.18.4-1","1:1.18.5-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-77630.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
