Description

USN-1138-1 fixed a vulnerability in DBus-GLib. NetworkManager and ModemManager required rebuilding against the updated DBus-GLib to incorporate the changes.

It was discovered that DBus-GLib did not properly verify the access flag of exported GObject properties under certain circumstances. A local attacker could exploit this to bypass intended access restrictions or possibly cause a denial of service.

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.
