FKIE_CVE-2009-0758
Vulnerability from fkie_nvd - Published: 2009-03-03 16:30 - Updated: 2026-06-16 23:05
Severity
Summary
The 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.
