avahi-daemon version 0.6.23
Description
The issue is related to the originates from local legacy unicast socket function in avahi-daemon, which does not properly handle the network byte order of a port number when processing incoming multicast packets.

The vulnerability can be exploited remotely and may lead to disruption of protected information availability.

For avahi-daemon versions 0.6.23 through 0.6.24-r2, update to version 0.6.24-r2 or later to resolve the issue.
At the moment, there is no information about additional mitigation measures for this vulnerability.
