avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE), not the upstream Avahi product. El archivo avahi-daemon-check-dns.sh en el paquete Debian avahi a versiones hasta 0.8-4, es ejecutado como root por medio de /etc/network/if-up.d/avahi-daemon, y permite a un atacante local causar una denegación de servicio o crear archivos vacíos arbitrarios por medio de un ataque de tipo symlink en archivos bajo /run/avahi-daemon. NOTA: esto solo afecta al empaquetado de Debian GNU/Linux (usado indirectamente por SUSE), no al producto de Avahi previo • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=982796 https://bugs.launchpad.net/ubuntu/+source/avahi/+bug/1870824 https://bugzilla.suse.com/show_bug.cgi?id=1180827 https://lists.debian.org/debian-lts-announce/2022/06/msg00009.html https://metadata.ftp-master.debian.org/changelogs/main/a/avahi/avahi_0.8-4_changelog https://packages.debian.org/bullseye/avahi-daemon https://packages.debian.org/buster/avahi-daemon https://packages.debian.org/sid/avahi-daemon https://secu • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVSS: 9.1EPSS: 6%CPEs: 7EXPL: 1CVE-2017-6519 – avahi: Multicast DNS responds to unicast queries outside of local network
https://notcve.org/view.php?id=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. • https://bugzilla.redhat.com/show_bug.cgi?id=1426712 https://github.com/lathiat/avahi/issues/203 https://github.com/lathiat/avahi/issues/203#issuecomment-449536790 https://lists.apache.org/thread.html/r1b103833cb5bc8466e24ff0ecc5e75b45a705334ab6a444e64e840a0%40%3Cissues.bookkeeper.apache.org%3E https://usn.ubuntu.com/3876-1 https://usn.ubuntu.com/3876-2 https://www.secfu.net/advisories https://access.redhat.com/security/cve/CVE-2017-6519 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-346: Origin Validation Error •
