The Linux kernel has a security flaw in all versions used on SUSE
products excluding the upcoming SUSE LINUX 8.2 distribution. The flaw
is known as ptrace/modprobe bug: The local attacker can use ptrace and
attach to a modprobe process that is spawned if the user triggers the
loading of a kernel module using the kmod kernel module subsystem.
This can be done by asking for network protocols that are supplied by
kernel modules which are not loaded (yet). The vulnerability allows
the attacker to execute arbitrary commands as root." );

"A number of vulnerabilities have been found in the Linux 2.2 kernel
that have been addressed with the latest 2.2.25 release.

A bug in the kernel module loader code could allow a local user to
gain root privileges. This is done by a local user using ptrace and
attaching to a modprobe process that is spawned if the user triggers
the loading of a kernel module.

A temporary workaround can be used to defend against this flaw. It is
possible to temporarily disable the kmod kernel module loading
subsystem in the kernel after all of the required kernel modules have
been loaded. Be sure that you do not need to load additional kernel
modules after implementing this workaround. To use it, as root 
execute :

echo /no/such/file >/proc/sys/kernel/modprobe

To automate this, you may wish to add it as the last line of the
/etc/rc.d/rc.local file. You can revert this change by replacing the
content '/sbin/modprobe' in the /proc/sys/kernel/modprobe file. The
root user can still manually load kernel modules with this workaround
in place.

As well, multiple ethernet device drivers do not pad frames with null
bytes, which could allow remote attackers to obtain information from
previous packets or kernel memory by using malformed packets.

Finally, the 2.2 kernel allows local users to cause a crash of the
host system by using the mmap() function with a PROT_READ parameter to
access non-readable memory pages through the /proc/pid/mem interface.

All users are encouraged to upgrade to the latest kernel version
provided.

NOTE: that this kernel is not binary compatible with the previous
version. For this reason, the kernel has a different version number
and will not be installed automatically as part of the normal upgrade
process. Any custom modules will need to be rebuilt in order to work
with the new kernel. New PCMCIA modules are provided for all of the
above kernels.

NOTE: A system reboot will be required immediately after the upgrade
in order to replace the running kernel. Remember to read carefully and
follow the instructions given during the kernel upgrade process."

arbitrary processes via a binary compatibility interface (lcall).

CAN-2003-0001: Multiple ethernet Network Interface Card (NIC) device
drivers do not pad frames with null bytes, which allows remote
attackers to obtain information from previous packets or kernel memory
by using malformed packets.

CAN-2003-0127: The kernel module loader allows local users to gain
root privileges by using ptrace to attach to a child process that is
spawned by the kernel.

CAN-2003-0244: The route cache implementation in Linux 2.4, and the
Netfilter IP conntrack module, allows remote attackers to cause a
denial of service (CPU consumption) via packets with forged source
addresses that cause a large number of hash table collisions related
to the PREROUTING chain.

CAN-2003-0246: The ioperm system call in Linux kernel 2.4.20 and
earlier does not properly restrict privileges, which allows local
users to gain read or write access to certain I/O ports.

CAN-2003-0247: Vulnerability in the TTY layer of the Linux kernel 2.4
allows attackers to cause a denial of service ('kernel oops').

CAN-2003-0248: The mxcsr code in Linux kernel 2.4 allows attackers to
modify CPU state registers via a malformed address.

CAN-2003-0364: The TCP/IP fragment reassembly handling in the Linux

"A bug in the kernel module loader code could allow a local user to
gain root privileges. This is done by a local user using ptrace and
attaching to a modprobe process that is spawned if the user triggers
the loading of a kernel module.

A temporary workaround can be used to defend against this flaw. It is
possible to temporarily disable the kmod kernel module loading
subsystem in the kernel after all of the required kernel modules have
been loaded. Be sure that you do not need to load additional kernel
modules after implementing this workaround. To use it, as root 
execute :

echo /no/such/file >/proc/sys/kernel/modprobe

To automate this, you may wish to add it as the last line of the
/etc/rc.d/rc.local file. You can revert this change by replacing the
content '/sbin/modprobe' in the /proc/sys/kernel/modprobe file. The
root user can still manually load kernel modules with this workaround
in place.

This update applies a patch to correct the problem. All users should
upgrade. Please note that the Mandrake Linux 9.1 kernel already has
this patch, and an updated kernel for Mandrake Linux 8.2 will be
available shortly.

For instructions on how to upgrade your kernel in Mandrake Linux,
please refer to :

http://www.mandrakesecure.net/en/kernelupdate.php

Update :

Kernels are now available for Mandrake Linux 8.2, 8.2/PPC, and Multi-
Network Firewall 8.2.

As well, the previously noted instructions for temporarily working
around the vulnerability are not completely accurate as they only
defend against a certain type of attack making use of this problem.
Users should upgrade to the update kernels, however if you are unable
to upgrade you may wish to look into the self-compiled
no-ptrace-module.c[1] that is loaded into a running kernel."

"Several serious problems have been discovered in the Linux kernel.
This update takes care of Linux 2.4.16 for the ARM architecture. The
Common Vulnerabilities and Exposures project identifies the following
problems that will be fixed with this update :

  - CAN-2003-0127
    The kernel module loader allows local users to gain root
    privileges by using ptrace to attach to a child process
    that is spawned by the kernel.

  - CAN-2004-0003

    A vulnerability has been discovered in the R128 DRI
    driver in the Linux kernel which could potentially lead
    an attacker to gain unauthorised privileges. Alan Cox
    and Thomas Biege developed a correction for this.

  - CAN-2004-0010

    Arjan van de Ven discovered a stack-based buffer
    overflow in the ncp_lookup function for ncpfs in the
    Linux kernel, which could lead an attacker to gain
    unauthorised privileges. Petr Vandrovec developed a
    correction for this.

  - CAN-2004-0109

    zen-parse discovered a buffer overflow vulnerability in
    the ISO9660 filesystem component of Linux kernel which
    could be abused by an attacker to gain unauthorised root
    access. Sebastian Krahmer and Ernie Petrides developed a
    correction for this.

  - CAN-2004-0177

    Solar Designer discovered an information leak in the
    ext3 code of Linux. In a worst case a local attacker
    could obtain sensitive information (such as
    cryptographic keys in another worst case) which would
    otherwise never hit disk media. Theodore Ts'o developed
    a correction for this.

  - CAN-2004-0178

    Andreas Kies discovered a denial of service condition in
    the Sound Blaster driver in Linux. He also developed a
    correction for this.

These problems are also fixed by upstream in Linux 2.4.26 and will be
fixed in Linux 2.6.6.

The following security matrix explains which kernel versions for which
architectures are already fixed and which will be removed instead.

  - CAN-2002-1380: Linux kernel 2.2.x allows local users to
    cause a denial of service (crash) by using the mmap()
    function with a PROT_READ parameter to access
    non-readable memory pages through the /proc/pid/mem
    interface.
  - CVE-2002-0429: The iBCS routines in
    arch/i386/kernel/traps.c for Linux kernels 2.4.18 and
    earlier on x86 systems allow local users to kill
    arbitrary processes via a binary compatibility interface
    (lcall)

  - CAN-2003-0001: Multiple ethernet Network Interface Card
    (NIC) device drivers do not pad frames with null bytes,
    which allows remote attackers to obtain information from
    previous packets or kernel memory by using malformed
    packets

  - CAN-2003-0127: The kernel module loader allows local
    users to gain root privileges by using ptrace to attach
    to a child process that is spawned by the kernel

  - CAN-2003-0244: The route cache implementation in Linux
    2.4, and the Netfilter IP conntrack module, allows
    remote attackers to cause a denial of service (CPU
    consumption) via packets with forged source addresses
    that cause a large number of hash table collisions
    related to the PREROUTING chain

  - CAN-2003-0246: The ioperm system call in Linux kernel
    2.4.20 and earlier does not properly restrict
    privileges, which allows local users to gain read or
    write access to certain I/O ports.

  - CAN-2003-0247: vulnerability in the TTY layer of the
    Linux kernel 2.4 allows attackers to cause a denial of
    service ('kernel oops')

  - CAN-2003-0248: The mxcsr code in Linux kernel 2.4 allows
    attackers to modify CPU state registers via a malformed
    address.

  - CAN-2003-0364: The TCP/IP fragment reassembly handling
    in the Linux kernel 2.4 allows remote attackers to cause
    a denial of service (CPU consumption) via certain
    packets that cause a large number of hash table
    collisions

"The IA-64 maintainers fixed several security related bugs in the Linux
kernel 2.4.17 used for the IA-64 architecture, mostly by backporting
fixes from 2.4.18. The corrections are listed below with the
identification from the Common Vulnerabilities and Exposures (CVE)
project :

  - CAN-2003-0001 :
    Multiple ethernet network interface card (NIC) device
    drivers do not pad frames with null bytes, which allows
    remote attackers to obtain information from previous
    packets or kernel memory by using malformed packets, as
    demonstrated by Etherleak.

  - CAN-2003-0018 :

    Linux kernel 2.4.10 through 2.4.21-pre4 does not
    properly handle the O_DIRECT feature, which allows local
    attackers with write privileges to read portions of
    previously deleted files, or cause file system
    corruption.

  - CAN-2003-0127 :

    The kernel module loader in Linux kernel 2.2.x before
    2.2.25, and 2.4.x before 2.4.21, allows local users to
    gain root privileges by using ptrace to attach to a
    child process which is spawned by the kernel.

  - CAN-2003-0461 :

    The virtual file /proc/tty/driver/serial in Linux 2.4.x
    reveals the exact number of characters used in serial
    links, which could allow local users to obtain
    potentially sensitive information such as the length of
    passwords.

  - CAN-2003-0462 :

    A race condition in the way env_start and env_end
    pointers are initialized in the execve system call and
    used in fs/proc/base.c on Linux 2.4 allows local users
    to cause a denial of service (crash).

  - CAN-2003-0476 :

    The execve system call in Linux 2.4.x records the file
    descriptor of the executable process in the file table
    of the calling process, which allows local users to gain
    read access to restricted file descriptors.

  - CAN-2003-0501 :

    The /proc filesystem in Linux allows local users to
    obtain sensitive information by opening various entries
    in /proc/self before executing a setuid program, which
    causes the program to fail to change the ownership and
    permissions of those entries.

  - CAN-2003-0550 :

    The STP protocol, as enabled in Linux 2.4.x, does not
    provide sufficient security by design, which allows
    attackers to modify the bridge topology.

  - CAN-2003-0551 :

    The STP protocol implementation in Linux 2.4.x does not
    properly verify certain lengths, which could allow
    attackers to cause a denial of service.

  - CAN-2003-0552 :

    Linux 2.4.x allows remote attackers to spoof the bridge
    Forwarding table via forged packets whose source
    addresses are the same as the target.

  - CAN-2003-0961 :

    An integer overflow in brk system call (do_brk function)
    for Linux kernel 2.4.22 and earlier allows local users
    to gain root privileges.

  - CAN-2003-0985 :

    The mremap system call (do_mremap) in Linux kernel 2.4
    and 2.6 does not properly perform boundary checks, which
    allows local users to cause a denial of service and
    possibly gain privileges by causing a remapping of a
    virtual memory area (VMA) to create a zero length VMA."

    earlier on x86 systems allow local users to kill
    arbitrary processes via a binary compatibility interface
    (lcall)
  - CAN-2003-0001: Multiple ethernet Network Interface Card
    (NIC) device drivers do not pad frames with null bytes,
    which allows remote attackers to obtain information from
    previous packets or kernel memory by using malformed

    users to gain root privileges by using ptrace to attach
    to a child process that is spawned by the kernel

  - CAN-2003-0244: The route cache implementation in Linux
    2.4, and the Netfilter IP conntrack module, allows
    remote attackers to cause a denial of service (CPU
    consumption) via packets with forged source addresses
    that cause a large number of hash table collisions
    related to the PREROUTING chain

  - CAN-2003-0246: The ioperm system call in Linux kernel
    2.4.20 and earlier does not properly restrict
    privileges, which allows local users to gain read or
    write access to certain I/O ports.

  - CAN-2003-0247: vulnerability in the TTY layer of the
    Linux kernel 2.4 allows attackers to cause a denial of
    service ('kernel oops')

  - CAN-2003-0248: The mxcsr code in Linux kernel 2.4 allows
    attackers to modify CPU state registers via a malformed
    address.

  - CAN-2003-0364: The TCP/IP fragment reassembly handling
    in the Linux kernel 2.4 allows remote attackers to cause
    a denial of service (CPU consumption) via certain
    packets that cause a large number of hash table
    collisions
