tag_insight = "system-config-firewall is a graphical user interface for basic firewall
  setup.

  It was found that system-config-firewall used the Python pickle module in
  an insecure way when sending data (via D-Bus) to the privileged back-end
  mechanism. A local user authorized to configure firewall rules using
  system-config-firewall could use this flaw to execute arbitrary code with
  root privileges, by sending a specially-crafted serialized object.
  (CVE-2011-2520)

  Red Hat would like to thank Marco Slaviero of SensePost for reporting this
  issue.

  This erratum updates system-config-firewall to use JSON (JavaScript Object
  Notation) for data exchange, instead of pickle. Therefore, an updated
  version of system-config-printer that uses this new communication data
  format is also provided in this erratum.

  Users of system-config-firewall are advised to upgrade to these updated
  packages, which contain a backported patch to resolve this issue. Running
  instances of system-config-firewall must be restarted before the utility
  will be able to communicate with its updated back-end.";
