"It was discovered that the D-Bus library honored environment settings
even when running with elevated privileges. A local attacker could
possibly use this flaw to escalate their privileges, by setting
specific environment variables before running a setuid or setgid
application linked against the D-Bus library (libdbus).
(CVE-2012-3524)

Note: With this update, libdbus ignores environment variables when
used by setuid or setgid applications. The environment is not ignored
when an application gains privileges via file system capabilities;
however, no application shipped in Red Hat Enterprise Linux 6 gains
privileges via file system capabilities.

We would like to thank Sebastian Krahmer of the SUSE Security Team for
reporting this issue.

For the update to take effect, all running instances of dbus-daemon
and all running applications using the libdbus library must be
restarted, or the system rebooted."
