Synopsis :

The remote Oracle Linux host is missing one or more security updates.

Description :

From Red Hat Security Advisory 2011:0376 :

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 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.
