CVE-2017-6519Cri0.599.10.01May 1, 2017avahi-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.
CVE-2026-34933Med0.295.50.00Apr 3, 2026Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. Prior to version 0.9-rc4, any unprivileged local user can crash avahi-daemon by sending a single D-Bus method call with conflicting publish flags. This issue has been patched in version 0.9-rc4.
CVE-2008-50810.09—0.77Dec 17, 2008The 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.
CVE-2011-10020.05—0.68Feb 22, 2011avahi-core/socket.c in avahi-daemon in Avahi before 0.6.29 allows remote attackers to cause a denial of service (infinite loop) via an empty mDNS (1) IPv4 or (2) IPv6 UDP packet to port 5353. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-2244.
CVE-2026-244010.00—0.00Jan 24, 2026Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In versions 0.9rc2 and below, avahi-daemon can be crashed via a segmentation fault by sending an unsolicited mDNS response containing a recursive CNAME record, where the alias and canonical name point to the same domain (e.g., "h.local" as a CNAME for "h.local"). This causes unbounded recursion in the lookup_handle_cname function, leading to stack exhaustion. The vulnerability affects record browsers where AVAHI_LOOKUP_USE_MULTICAST is set explicitly, which includes record browsers created by resolvers used by nss-mdns. This issue is patched in commit 78eab31128479f06e30beb8c1cbf99dd921e2524.
CVE-2010-22440.00—0.01Jul 8, 2010The 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.
CVE-2009-07580.00—0.01Mar 3, 2009The originates_from_local_legacy_unicast_socket function in avahi-core/server.c in avahi-daemon 0.6.23 does not account for the network byte order of a port number when processing incoming multicast packets, which allows remote attackers to cause a denial of service (network bandwidth and CPU consumption) via a crafted legacy unicast mDNS query packet that triggers a multicast packet storm.
CVE-2007-33720.00—0.00Jun 22, 2007The 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.
CVE-2006-68700.00—0.06Dec 31, 2006The 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.
CVE-2006-54610.00—0.00Nov 14, 2006Avahi 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.
CVE-2006-22880.00—0.00May 10, 2006Avahi before 0.6.10 allows local users to cause a denial of service (mDNS/DNS-SD service disconnect) via unspecified mDNS name conflicts.
CVE-2006-22890.00—0.00May 10, 2006Buffer overflow in avahi-core in Avahi before 0.6.10 allows local users to execute arbitrary code via unknown vectors.
