2017-05-01 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, Ubuntu_linux 9.1
2021-05-07 CVE-2021-3502 A flaw was found in avahi 0.8-5. A reachable assertion is present in avahi_s_host_name_resolver_start function allowing a local attacker to crash the avahi service by requesting hostname resolutions through the avahi socket or dbus methods for invalid hostnames. The highest threat from this vulnerability is to the service availability. Avahi 5.5
2021-06-02 CVE-2021-3468 A flaw was found in avahi in versions 0.6 up to 0.8. The event used to signal the termination of the client connection on the avahi Unix socket is not correctly handled in the client_work function, allowing a local attacker to trigger an infinite loop. The highest threat from this vulnerability is to the availability of the avahi service, which becomes unresponsive after this flaw is triggered. Avahi, Debian_linux 5.5
2023-05-26 CVE-2023-1981 A vulnerability was found in the avahi library. This flaw allows an unprivileged user to make a dbus call, causing the avahi daemon to crash. Avahi, Fedora, Enterprise_linux 5.5
2021-02-17 CVE-2021-26720 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. Avahi, Debian_linux 7.8
2010-07-08 CVE-2010-2244 The AvahiDnsPacket function in avahi-core/socket.c in avahi-daemon in Avahi 0.6.16 and 0.6.25 allows remote attackers to cause a denial of service (assertion failure and daemon exit) via a DNS packet with an invalid checksum followed by a DNS packet with a valid checksum, a different vulnerability than CVE-2008-5081. Avahi N/A
2008-12-17 CVE-2008-5081 The originates_from_local_legacy_unicast_socket function (avahi-core/server.c) in avahi-daemon in Avahi before 0.6.24 allows remote attackers to cause a denial of service (crash) via a crafted mDNS packet with a source port of 0, which triggers an assertion failure. Avahi N/A
2007-06-22 CVE-2007-3372 The Avahi daemon in Avahi before 0.6.20 allows attackers to cause a denial of service (exit) via empty TXT data over D-Bus, which triggers an assert error. Avahi N/A
2006-12-31 CVE-2006-6870 The consume_labels function in avahi-core/dns.c in Avahi before 0.6.16 allows remote attackers to cause a denial of service (infinite loop) via a crafted compressed DNS response with a label that points to itself. Avahi N/A
2006-11-14 CVE-2006-5461 Avahi before 0.6.15 does not verify the sender identity of netlink messages to ensure that they come from the kernel instead of another process, which allows local users to spoof network changes to Avahi. Avahi N/A
