RHEL 5 : dbus-glib (RHSA-2010:0616)

low Nessus Plugin ID 48313

Language:

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

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

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.

dbus-glib is an add-on library to integrate the standard D-Bus library with the GLib main loop and threading model. NetworkManager is a network link manager that attempts to keep a wired or wireless network connection active at all times.

It was discovered that dbus-glib did not enforce the 'access' flag on exported GObject properties. If such a property were read/write internally but specified as read-only externally, a malicious, local user could use this flaw to modify that property of an application.
Such a change could impact the application's behavior (for example, if an IP address were changed the network may not come up properly after reboot) and possibly lead to a denial of service. (CVE-2010-1172)

Due to the way dbus-glib translates an application's XML definitions of service interfaces and properties into C code at application build time, applications built against dbus-glib that use read-only properties needed to be rebuilt to fully fix the flaw. As such, this update provides NetworkManager packages that have been rebuilt against the updated dbus-glib packages. No other applications shipped with Red Hat Enterprise Linux 5 were affected.

All dbus-glib and NetworkManager users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue. Running instances of NetworkManager must be restarted (service NetworkManager restart) for this update to take effect.

Solution

Update the affected packages.
