tag_insight = "D-Bus is a system for sending messages between applications. It is used for
  the system-wide message bus service and as a per-user-login-session
  messaging facility.

  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.
  
  Red Hat would like to thank Sebastian Krahmer of the SUSE Security Team for
  reporting this issue.
  
  All users are advised to upgrade to these updated packages, which contain a
  backported patch to correct 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.";
