Topic

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.

Description

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.
