Due to insufficient validation in the `recv_igmp()` function in src/igmpproxy.c, an invalid group record type can trigger a NULL pointer dereference when logging the address using `inet_fmtsrc()`. This vulnerability can be exploited by sending malformed multicast traffic to a host running igmpproxy, leading to a crash. igmpproxy is used in various embedded networking environments and consumer-grade IoT devices (such as home routers and media gateways) to handle multicast traffic for IPTV and other streaming services. Affected devices that rely on unpatched versions of igmpproxy may be vulnerable to remote denial-of-service attacks across a LAN ."}, {"lang": "es", "value": "igmpproxy 0.4 anterior al commit 2b30c36 permite a atacantes remotos causar una denegaci\u00f3n de servicio (ca\u00edda de la aplicaci\u00f3n) a trav\u00e9s de un paquete de informe de membres\u00eda IGMPv3 manipulado con una direcci\u00f3n de origen maliciosa. Debido a una validaci\u00f3n insuficiente en la funci\u00f3n recv_igmp() en src/igmpproxy.c, un tipo de registro de grupo inv\u00e1lido puede desencadenar una desreferencia de puntero NULL al registrar la direcci\u00f3n usando inet_fmtsrc(). Esta vulnerabilidad puede ser explotada enviando tr\u00e1fico multicast malformado a un host que ejecuta igmpproxy, lo que lleva a una ca\u00edda. igmpproxy se utiliza en varios entornos de red embebidos y dispositivos IoT de grado de consumidor (como routers dom\u00e9sticos y pasarelas de medios) para manejar tr\u00e1fico multicast para IPTV y otros servicios de streaming. Dispositivos afectados que dependen de versiones sin parchear de igmpproxy pueden ser vulnerables a ataques remotos de denegaci\u00f3n de servicio a trav\u00e9s de una LAN."}], "lastModified": "2026-10-13T11:10:00.203", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:pali:igmpproxy:0.4:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "54643BDE-3F80-448D-91E0-BC06F1277847"}], "operator": "OR"}]}], "sourceIdentifier": "cve@mitre.org"}
