{"id":"DEBIAN-CVE-2026-57486","details":"pupnp is an SDK for development of UPnP device and control point applications. Prior to 2.0.2, ixmlNode_compare in ixml/src/node.c passes the nullable nodeValue, namespaceURI, prefix, and localName fields directly to strcmp. Non-namespaced attributes created by ixmlDocument_createAttribute legitimately leave those fields NULL. When ixmlElement_removeAttributeNode compares two distinct attribute objects with the same nodeName through find_condition_node, the pointer-identity shortcut does not apply and the comparison dereferences NULL, causing a process crash when application handling of attacker-controlled XML reaches this path. This issue is fixed in 2.0.2.","modified":"2026-10-17T05:00:06.908884515Z","published":"2026-10-16T16:18:44.510Z","upstream":["CVE-2026-57486"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-57486"}],"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-2026-57486.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-2026-57486.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"}]}
