RHSA-2009:0013: Moderate: avahi security update

First published: Mon Jan 12 2009(Updated: )

Avahi is an implementation of the DNS Service Discovery and Multicast DNS<br>specifications for Zeroconf Networking. It facilitates service discovery on<br>a local network. Avahi and Avahi-aware applications allow you to plug your<br>computer into a network and, with no configuration, view other people to<br>chat with, see printers to print to, and find shared files on other computers.<br>Hugo Dias discovered a denial of service flaw in avahi-daemon. A remote<br>attacker on the same local area network (LAN) could send a<br>specially-crafted mDNS (Multicast DNS) packet that would cause avahi-daemon<br>to exit unexpectedly due to a failed assertion check. (CVE-2008-5081)<br>All users are advised to upgrade to these updated packages, which contain a<br>backported patch which resolves this issue. After installing the update,<br>avahi-daemon will be restarted automatically.<br>
