CVE-2017-6519

avahi-daemon in Avahi through 0.6.32 and 0.7 inadvertently responds to IPv6 unicast queries with source addresses that are not on-link, which allows remote attackers to cause a denial of service (traffic amplification) and may cause information leakage by obtaining potentially sensitive information from the responding device via port-5353 UDP packets. NOTE: this may overlap CVE-2015-2809.

avahi-daemon en Avahi, hasta las versiones 0.6.32 y 0.7, responde a consultas IPv6 unicast arbitrarias de manera inadvertida con direcciones de origen que no se pueden resolver localmente, lo que permite a los atacantes remotos provocar una denegación de servicio (amplificación de tráfico) y puede conducir a una fuga de información, obteniendo información potencialmente sensible del dispositivo de respuesta mediante paquetes UDP del puerto 5353. NOTA: podría solaparse con CVE-2015-2809.
