1. Topic:

Updated kernel packages that fix several security issues are now
available.

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

2. Relevant releases/architectures:

Fedora Core 3 - i386, x86_64

3. Problem description:

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

- a flaw in network IGMP processing that a allowed a remote user on the
local network to cause a denial of service (disabling of multicast
reports) if the system is running multicast applications (CVE-2002-2185)

- a flaw in procfs handling during unloading of modules that allowed a
local user to cause a denial of service or potentially gain privileges
(CVE-2005-2709)

- a flaw in 32-bit-compat handling of the TIOCGDEV ioctl that allowed
a local user to cause a denial of service (crash) (CVE-2005-3044)

- a race condition in ip_vs_conn_flush that allowed a local user to
cause a denial of service (CVE-2005-3274)

- a flaw in mq_open system call that allowed a local user to cause a
denial of service (crash) (CVE-2005-3356)

- a flaw in set_mempolicy that allowed a local user on some 64-bit
architectures to cause a denial of service (crash) (CVE-2005-3358)

- a race condition in do_coredump in signal.c that allowed a local user
to cause a denial of service (crash) (CVE-2005-3527)

- a flaw in the auto-reap of child processes that allowed a local user
to cause a denial of service (crash) (CVE-2005-3784)

- a flaw in the POSIX timer cleanup handling that allowed a local user
to cause a denial of service (crash) (CVE-2005-3805)

- a flaw in the IPv6 flowlabel code that allowed a local user to cause a
denial of service (crash) (CVE-2005-3806)

- a memory leak in the VFS file lease handling that allowed a local user
to cause a denial of service (CVE-2005-3807)

- a flaw in file lease time-out handling that allowed a local user to
cause a denial of service (log file overflow) (CVE-2005-3857)

- a flaw in procfs handling that allowed a local user to read kernel
memory (CVE-2005-4605)

- a memory disclosure flaw in dm-crypt that allowed a local user to
obtain sensitive information about a cryptographic key (CVE-2006-0095)

- a flaw while constructing an ICMP response that allowed remote users
to cause a denial of service (crash) (CVE-2006-0454)

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

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

To install kernel packages manually, use "rpm -ivh lt;packagegt;" and modify
system settings to boot the kernel you have installed. To do this, edit
/boot/grub/grub.conf and change the default entry to "default=0" (or, if
you have chosen to use LILO as your boot loader, edit /etc/lilo.conf and
run lilo)

Please note that this update is also available via yum and apt. Many
people find this an easier way to apply updates. To use yum issue:

yum update

or to use apt:

apt-get update; apt-get upgrade

This will start an interactive process that will result in the
appropriate RPMs being upgraded on your system. This assumes that you
have yum or apt-get configured for obtaining Fedora Legacy content.
Please visit http://www.fedoralegacy.org/docs for directions on how to
configure yum and apt-get.

Note that this may not automatically pull the new kernel in if you have
configured apt/yum to ignore kernels. If so, follow the manual
instructions above.

These packages are GPG signed by Fedora Legacy for security. Our key is
available from http://www.fedoralegacy.org/about/security.php

You can verify each package with the following command:

rpm --checksig -v lt;filenamegt;

If you only wish to verify that each package has not been corrupted or
tampered with, examine only the sha1sum with the following command:

sha1sum lt;filenamegt;
