<title>Avahi: Denial of Service</title>

consumption.

<affected>
<package name="net-dns/avahi" auto="yes" arch="*">
<unaffected range="ge">0.6.24-r2</unaffected>

<background>
<p>
Avahi is a system that facilitates service discovery on a local
network.
</p>
</background>
<description>
<p>
Rob Leslie reported that the
originates_from_local_legacy_unicast_socket() function in
avahi-core/server.c does not account for the network byte order of a
port number when processing incoming multicast packets, leading to a
multicast packet storm.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could send specially crafted legacy unicast mDNS
query packets to the Avahi daemon, resulting in a Denial of Service due
to network bandwidth and CPU consumption.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Avahi users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/avahi-0.6.24-r2"</code>
</resolution>
