    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:

    A race condition was discovered. Local users could use this flaw to read
    the environment variables of another process that is still spawning via
    /proc/.../cmdline. (CAN-2004-1058)

    An integer overflow was discovered in the vc_resize function. A local
    user could cause a denial of service (kernel crash) via a short new
    screen value, which leads to a buffer overflow. (CAN-2004-1333)

    A flaw was discovered in the Linux PPP driver. On systems allowing
    remote users to connect to a server using ppp, a remote client could
    cause a denial of service (system crash). (CAN-2005-0384)

    A flaw was discovered in ext2 filesystem support. When a new directory
    is created, the ext2 block written to disk is not initialized, leading
    to an information leak. (CAN-2005-0400)

    A flaw in fragment queuing was discovered affecting the netfilter
    subsystem. On systems configured to filter or process network packets
    (for example those configured to do firewalling), a remote attacker
    could send a carefully crafted set of fragmented packets to a machine
    and cause a denial of service (system crash). In order to sucessfully
    exploit this flaw, the attacker would need to know (or guess) some
    aspects of the firewall ruleset in place on the target system to be able
    to craft the right fragmented packets. (CAN-2005-0449)

    The moxa char driver was missing a CAP_SYS_RAWIO check which could allow
    a local user the ability to do things like replace the firmware.
    (CAN-2005-0504)

    A flaw when freeing a pointer in load_elf_library was discovered. A
    local user could potentially use this flaw to cause a denial of service
    (system crash). (CAN-2005-0749)

    A flaw was discovered in the bluetooth driver system. On system where
    the bluetooth modules are loaded, a local user could use this flaw to
    gain elevated (root) privileges. (CAN-2005-0750)

    Michal Zalewski discovered some flaws in the iso9660 filesystem. These
    flaws could allow a malicious iso filesystem to cause a DoS or
    potentially execute arbitrary code if mounted/examined. (CAN-2005-0815)

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

    Please note that the fix for CAN-2005-0449 required changing the
    external symbol linkages (kernel module ABI) for the ip_defrag()
    and ip_ct_gather_frags() functions. Any third-party module using either
    of these would also need to be fixed.

    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:

        sha1sum <filename>
