RHEL 5 : avahi (RHSA-2009:0013)

high Nessus Plugin ID 35358

Synopsis

The remote Red Hat host is missing a security update for avahi.

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2009:0013 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL avahi package based on the guidance in RHSA-2009:0013.
