--------------------------------------------------------------------- 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
Fedora Core 1 - i386

3. Problem description:

This update includes fixes for several security issues:

The ext3 code in kernels before 2.4.26 did not properly initialize
journal descriptor blocks. A privileged local user could read portions
of kernel memory. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CAN-2004-0177 to this issue.

Conectiva discovered flaws in certain USB drivers affecting kernels
prior to 2.4.27 which used the copy_to_user function on uninitialized
structures. These flaws could allow local users to read small amounts
of kernel memory. (CAN-2004-0685)

Multiple race conditions in the terminal layer could allow local users
to obtain portions of kernel data via a TIOCSETD ioctl call to a
terminal interface that is being accessed by another thread. This could
also allow remote attackers to cause a denial of service (panic) by
switching from console to PPP line discipline, then quickly sending data
that is received during the switch. (CAN-2004-0814)

Stefan Esser discovered various flaws including buffer overflows in
the smbfs driver affecting kernels prior to 2.4.28. A local user may be
able to cause a denial of service (crash) or possibly gain privileges.
In order to exploit these flaws the user would require control of
a connected Samba server. (CAN-2004-0883, CAN-2004-0949)

ISEC security research and Georgi Guninski independantly discovered a
flaw in the scm_send function in the auxiliary message layer. A local
user could create a carefully crafted auxiliary message which could
cause a denial of service (system hang). (CAN-2004-1016)

Multiple overflows were discovered and corrected in the io_edgeport
driver. (CAN-2004-1017)

The Direct Rendering Manager (DRM) driver does not properly check the
DMA lock, which could allow remote attackers or local users to cause a
denial of service (X Server crash) and possibly modify the video output.
(CAN-2004-1056)

A missing serialization flaw in unix_dgram_recvmsg was discovered that
affects kernels prior to 2.4.28. A local user could potentially make
use of a race condition in order to gain privileges. (CAN-2004-1068)

Paul Starzetz of iSEC discovered various flaws in the ELF binary loader
affecting kernels prior to 2.4.28. A local user could use these flaws to
gain read access to executable-only binaries or possibly gain
privileges. (CAN-2004-1070, CAN-2004-1071, CAN-2004-1072, CAN-2004-1073,
CAN-2004-1074)

ISEC security research discovered multiple vulnerabilities in the IGMP
functionality of the kernels. These flaws could allow a local user to
cause a denial of service (crash) or potentially gain privileges. Where
multicast applications are being used on a system, these flaws may also
allow remote users to cause a denial of service. (CAN-2004-1137)

Kirill Korotaev found a flaw in load_elf_binary affecting kernels prior
to 2.4.26. A local user could create a carefully crafted binary in such
a way that it would cause a denial of service (system crash).
(CAN-2004-1234)

iSEC Security Research discovered a VMA handling flaw in the uselib(2)
system call of the Linux kernel. A local user could make use of this
flaw to gain elevated (root) privileges. (CAN-2004-1235)

iSEC Security Research discovered a flaw in the page fault handler code
that could lead to local users gaining elevated (root) privileges on
multiprocessor machines. (CAN-2005-0001)

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 <package>" 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 <filename>

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