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:

Red Hat Linux 7.3 - i386
Red Hat Linux 9 - i386

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 recent Internet Draft by Fernando Gont recommended that ICMP Source
Quench messages be ignored by hosts. A patch to ignore these messages is
included. (CVE-2004-0791)

- flaws in the coda module that allowed denial-of-service attacks
(crashes) or local privilege escalations (CVE-2005-0124)

- a flaw between execve() syscall handling and core dumping of
ELF-format executables allowed local unprivileged users to cause a
denial of service (system crash) or possibly gain privileges
(CVE-2005-1263)

- a flaw in gzip/zlib handling internal to the kernel that may allow a
local user to cause a denial of service (crash) (CVE-2005-2458)

- a flaw in sendmsg() syscall handling on 64-bit systems that allowed
a local user to cause a denial of service or potentially gain
privileges (CVE-2005-2490)

- a flaw in exec() handling on some 64-bit architectures that allowed
a local user to cause a denial of service (crash) (CVE-2005-2708)

- 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 IPv6 network UDP port hash table lookups that allowed a
local user to cause a denial of service (hang) (CVE-2005-2973)

- a network buffer info leak using the orinoco driver that allowed
a remote user to possibly view uninitialized data (CVE-2005-3180)

- a flaw in the packet radio ROSE protocol that allowed a user to
trigger out-of-bounds errors. (CVE-2005-3273)

- a flaw in IPv4 network TCP and UDP netfilter handling that allowed
a local user to cause a denial of service (crash) (CVE-2005-3275)

- a minor info leak with the get_thread_area() syscall that allowed
a local user to view uninitialized kernel stack data (CVE-2005-3276)

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

- 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)

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;
