"Several security related problems have been fixed in the Linux kernel
2.4.17 used for the S/390 architecture, mostly by backporting fixes
from 2.4.18 and incorporating recent security fixes. The corrections
are listed below with the identification from the Common
Vulnerabilities and Exposures (CVE) project :

  - 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, as
    demonstrated by Etherleak.

  - 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 :

    A 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.

  - CAN-2003-0961 :

    An integer overflow in brk() system call (do_brk()
    function) for Linux allows a local attacker to gain root
    privileges. Fixed upstream in Linux 2.4.23.

  - CAN-2003-0985 :

    Paul Starzetz discovered a flaw in bounds checking in
    mremap() in the Linux kernel (present in version 2.4.x
    and 2.6.x) which may allow a local attacker to gain root
    privileges. Version 2.2 is not affected by this bug.
    Fixed upstream in Linux 2.4.24.

  - CAN-2004-0077 :

    Paul Starzetz and Wojciech Purczynski of isec.pl
    discovered a critical security vulnerability in the
    memory management code of Linux inside the mremap(2)
    system call. Due to missing function return value check
    of internal functions a local attacker can gain root
    privileges. Fixed upstream in Linux 2.4.25 and 2.6.3."

"These updated kernel packages address security vulnerabilites,
including two possible data corruption scenarios. In addition, a
number of drivers have been updated, improvements made to system
performance, and various issues have been resolved.

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

Two potential data corruption scenarios have been identified. These
scenarios can occur under heavy, complex I/O loads.

The first scenario only occurs while performing memory mapped file
I/O, where the file is simultaneously unlinked and the corresponding
file blocks reallocated. Furthermore, the memory mapped must be to a
partial page at the end of a file on an ext3 file system. As such, Red
Hat considers this scenario unlikely.

The second scenario was exhibited in systems with more than 4 GB of
memory with a storage controller capable of block device DMA above 4GB
(64-bit DMA). By restricting storage drivers to 32-bit DMA, the
problem was resolved. Prior to this errata, the SCSI subsystem was
already restricted to 32-bit DMA; this errata extends the restriction
to block drivers as well. The change consists of disabling 64-bit DMA
in the cciss driver (the HP SA5xxx and SA6xxx RAID controllers). The
performance implications of this change to the cciss driver are
minimal.

In addition, the following security vulnerabilities have been
addressed :

A flaw was found in several hash table implementations in the kernel
networking code. A remote attacker sending packets with carefully
chosen, forged source addresses could potentially cause every routing
cache entry to be hashed into the same hash chain. As a result, the
kernel would use a disproportionate amount of processor time to deal
with the new packets, leading to a remote denial-of-service (DoS)
attack. The Common Vulnerabilities and Exposures project
(cve.mitre.org) has assigned the name CVE-2003-0244 to this issue.

A flaw was also found in the 'ioperm' system call, which fails to
properly restrict privileges. This flaw can allow an unprivileged
local user to gain read and write access to I/O ports on the system.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CVE-2003-0246 to this issue.

In addition, the following drivers have been updated to the versions
indicated :

-aacraid: 0.9.9ac6-TEST -qlogic qla2100, qla2200, qla2300: 6.04.01
-aic7xxx_mod: 6.2.30 and aic79xx: 1.3.4 -ips: v6.00.26 -cpqfc: 2.1.2
-fusion: 2.05.00 -e100: 2.2.21-k1 -e1000: 5.0.43-k1, and added netdump
support -natsemi: 1.07+LK1.0.17 -cciss: 2.4.45. -cpqarray: 2.4.26

If the system is configured to use alternate drivers, we recommend
applying the kudzu errata RHEA-2003:132 prior to updating the kernel.

A number of edge conditions in the virtual memory system have been
identified and resolved. These included the elimination of memory
allocation failures occuring when the system had not depleted all of
the physical memory. This would typically lead to process creation and
network driver failures, and general performance degradation.
Additional memory reclamation improvements were introduced to further
smooth out the natural system performance degradation that occur under
memory exhaustion conditions.

In addition, the latest summit patches have been included.

All users should upgrade to these errata packages, which address these
issues."

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."

"A number of vulnerabilities have been discovered in the Linux kernel.

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.

This advisory covers only the powerpc architecture. Other
architectures will be covered by separate advisories."
