Description

Background

D-Bus is a message bus system which processes can use to talk to each other.

Description

It was discovered that a local attacker could manipulate symbolic links in their own home directory to bypass authentication and connect to a DBusServer with elevated privileges.

Impact

A local attacker can bypass authentication mechanisms and elevate privileges.

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-1.12.16"
