Background

D-Bus is a message bus system, a simple way for applications to talk to one another.

Description

D-Bus doesn’t validate the source of ActivationFailure signals.

Impact

A local attacker could possibly cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All D-Bus users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=sys-apps/dbus-1.8.16"
