RedHat: RHSA-2009-0013:01 Moderate: avahi security update
Summary
Avahi is an implementation of the DNS Service Discovery and Multicast DNS
specifications for Zeroconf Networking. It facilitates service discovery on
a local network. Avahi and Avahi-aware applications allow you to plug your
computer into a network and, with no configuration, view other people to
chat with, see printers to print to, and find shared files on other computers.
Hugo Dias discovered a denial of service flaw in avahi-daemon. A remote
attacker on the same local area network (LAN) could send a
specially-crafted mDNS (Multicast DNS) packet that would cause avahi-daemon
to exit unexpectedly due to a failed assertion check. (CVE-2008-5081)
All users are advised to upgrade to these updated packages, which contain a
backported patch which resolves this issue. After installing the update,
avahi-daemon will be restarted automatically.
Summary
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
This update is available via Red Hat Network. Details on how to use
