RHEL 5 / 6 : dbus (RHSA-2011:0376)

critical Nessus Plugin ID 52764

Synopsis

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

Description

The remote Redhat Enterprise Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0376 advisory.

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 discovered in the system for sending messages between applications. A local user could send a message with an excessive number of nested variants to the system-wide message bus, causing the message bus (and, consequently, any process using libdbus to receive messages) to abort. (CVE-2010-4352)

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.

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 dbus package based on the guidance in RHSA-2011:0376.
