Name        : avahi
Product     : Fedora 14
Version     : 0.6.27
Release     : 8.fc14
URL         : http://avahi.org
Summary     : Local network service discovery
Description :
Avahi is a system which facilitates service discovery on
a local network -- this means that you can plug your laptop or
computer into a network and instantly be able to view other people who
you can chat with, find printers to print to or find files being
shared. This kind of technology is already found in MacOS X (branded
'Rendezvous', 'Bonjour' and sometimes 'ZeroConf') and is very
convenient.

Update Information:

Fixes CVE-2011-1002.

The MITRE CVE dictionary describes this issue as:

avahi-core/socket.c in avahi-daemon in Avahi before 0.6.29 allows remote attackers to cause a denial of service (infinite loop) via an empty mDNS (1) IPv4 or (2) IPv6 UDP packet to port 5353. NOTE: this vulnerability exists because of an incorrect fix for CVE-2010-2244.

Find out more about CVE-2011-1002 from the MITRE CVE dictionary and NIST NVD.

This also disables gtk3 support. Unfortunately gtk3 support in F14 is broken and Avahi cannot be compiled against it. Since gtk3 will not be fixed in F14 anymore and nobody uses it we instead disable it in Avahi.
