Synopsis

Important: Updated kernel packages for Red Hat Enterprise Linux 3 Update 9

Type/Severity

Security Advisory Important

Topic

Updated kernel packages are now available as part of ongoing support and maintenance of Red Hat Enterprise Linux version 3. This is the ninth regular update.

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.

This is the ninth regular kernel update to Red Hat Enterprise Linux 3.

There were no new features introduced by this update. The only changes that have been included address critical customer needs or security issues (elaborated below).

Key areas affected by fixes in this update include the networking subsystem, dcache handling, the ext2 and ext3 file systems, the USB subsystem, ACPI handling, and the audit subsystem. There were also several isolated fixes in the tg3, e1000, megaraid_sas, and aacraid device drivers.

The following security bugs were fixed in this update:

  • a flaw in the cramfs file system that allowed invalid compressed data to cause memory corruption (CVE-2006-5823, low)

  • a flaw in the ext2 file system that allowed an invalid inode size to cause a denial of service (system hang) (CVE-2006-6054, low)

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

Note: The kernel-unsupported package contains various drivers and modules that are unsupported and therefore might contain security problems that have not been addressed.

All Red Hat Enterprise Linux 3 users are advised to upgrade their kernels to the packages associated with their machine architectures and configurations as listed in this erratum.
