  denial of service (crash). (CVE-2007-1592, Important)

  denial of service or potential privilege escalation. (CVE-2007-1217, Moderate)

• a flaw in the Bluetooth subsystem that allowed a local user to trigger an
  information leak. (CVE-2007-1353, Low)

• various flaws in the supported filesystems that allowed a local
  privileged user to cause a denial of service. (CVE-2006-6054, CVE-2006-6058,
  Low)

Red Hat would like to thank Ilja van Sprundel for reporting an issue fixed

issues.
