CentOS 5 : dbus (CESA-2011:1132)

medium Nessus Plugin ID 56269

Synopsis

The remote CentOS host is missing one or more security updates.

Description

Updated dbus packages that fix one security issue are now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.

D-Bus is a system for sending messages between applications. It is used for the system-wide message bus service and as a per-user-login-session messaging facility.

A denial of service flaw was found in the way the D-Bus library handled endianness conversion when receiving messages. A local user could use this flaw to send a specially crafted message to dbus-daemon or to a service using the bus, such as Avahi or NetworkManager, possibly causing the daemon to exit or the service to disconnect from the bus. (CVE-2011-2200)

All users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. For the update to take effect, all running instances of dbus-daemon and all running applications using the libdbus library must be restarted, or the system rebooted.

Solution

Update the affected dbus packages.
