CentOS Errata and Security Advisory CESA-2007:0436

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.
