Detail

Synopsis

A vulnerability has been found in D-Bus which allows local attackers to gain escalated privileges.

Background

D-Bus is a daemon providing a framework for applications to communicate with one another. GLib is a library providing a number of GNOME's core objects and functions.

Description

When libdbus is used in a setuid program, a user can gain escalated privileges by leveraging the DBUS_SYSTEM_BUS_ADDRESS variable. GLib can be used in a setuid context with D-Bus, and so can trigger this vulnerability. Please review the CVE identifier below for more details.

Impact

A local attacker could gain escalated privileges and execute arbitrary code.

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-1.6.8"

All GLib users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-libs/glib-2.32.4-r1"

Description: libdbus 1.5.x and earlier, when used in setuid or other privileged programs in X.org and possibly other products, allows local users to gain privileges and execute arbitrary code via the DBUS_SYSTEM_BUS_ADDRESS environment variable. NOTE: libdbus maintainers state that this is a vulnerability in the applications that do not cleanse environment variables, not in libdbus itself: "we do not support use of libdbus in setuid binaries that do not sanitize their environment before their first call into libdbus."
