Tracker summary

CVE-2009-0758 low priority: Debian including 1 source packages (avahi), 5 status rows across 5 suites (bookworm, bullseye, forky, sid, trixie): resolved 5.

Description:

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.
