  - 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.' (CVE-2012-3524)"
