(RHSA-2007:0673) Important: kernel security update

The Linux kernel handles the basic functions of the operating system.

These new kernel packages contain fixes for the security issues described
below:

• a flaw in IPV6 flow label handling that allowed a local user to
  cause a denial of service (crash). (CVE-2007-1592, Important)

• a flaw in the ISDN CAPI subsystem that allowed a remote user to cause a
  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)

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

Red Hat would like to thank Ilja van Sprundel for reporting an issue fixed
in this erratum.

All Red Hat Enterprise Linux 2.1 users are advised to upgrade their kernels
to these updated packages, which contain backported fixes to correct these
issues.
