Description

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. This update provides NetworkManager, ModemManager and DeviceKit-power packages that have been rebuilt against the updated dbus-glib packages.

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