CVE-2012-3524

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.”
