The remote Oracle Linux 5 / 6 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2013-0568 advisory.

    - Add patch to fix CVE-2013-0292

Tenable has extracted the preceding description block directly from the Oracle 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.

A flaw was found in the way dbus-glib filtered the message sender (message source subject) when the 'NameOwnerChanged' signal was received. This could trick a system service using dbus-glib (such as fprintd) into believing a signal was sent from a privileged process, when it was not. A local attacker could use this flaw to escalate their privileges. (CVE-2013-0292)

All running applications linked against dbus-glib, such as fprintd and NetworkManager, must be restarted for this update to take effect.

Updated dbus-glib 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 important 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.

dbus-glib is an add-on library to integrate the standard D-Bus library with the GLib main loop and threading model.

All dbus-glib users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. All running applications linked against dbus-glib, such as fprintd and NetworkManager, must be restarted for this update to take effect.

Updated dbus-glib packages fix security vulnerability :

A privilege escalation flaw was found in the way dbus-glib, the D-Bus add-on library to integrate the standard D-Bus library with the GLib thread abstraction and main loop, performed filtering of the message sender (message source subject), when the NameOwnerChanged signal was received. A local attacker could use this flaw to escalate their privileges (CVE-2013-0292).

The remote OracleVM system is missing necessary patches to address critical security updates :

  - Add patch to fix (CVE-2013-0292)

  - Resolves: #913072

Sebastian Krahmer and Bastien Nocera discovered that DBus-GLib did not properly validate the message sender when the 'NameOwnerChanged' signal was received. A local attacker could possibly use this issue to escalate their privileges.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
