Avahi is a system which facilitates service discovery on a local network via the mDNS/DNS-SD protocol suite. In 0.9-rc2 and earlier, avahi-daemon can be crashed by sending 2 unsolicited announcements with CNAME resource records 2 seconds apart.
A flaw was found in Avahi, a system that enables devices to discover services on a local network using the mDNS/DNS-SD (Multicast Domain Name System/DNS-based Service Discovery) protocols. A remote attacker can exploit this by sending two specific network messages, known as unsolicited announcements with CNAME resource records, within a two-second timeframe. This action can cause the avahi-daemon process to crash, leading to a Denial of Service (DoS) for the affected system.
