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 and possibly lead to a denial of service. 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 for this update to take effect.
