"Updated kernel packages that fix a number of security issues are now
available for Red Hat Enterprise Linux 2.1 (32-bit architectures).

This security advisory has been rated as having important security
impact by the Red Hat Security Response Team.

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)

* 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 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."
