    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:
    
    CAN-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 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.
    
    For the stable distribution (woody) these problems have been fixed in
    version 2.4.17-2.woody.3 of s390 images and in version
    0.0.20020816-0.woody.2 of the patch packages.
    
    For the unstable distribution (sid) these problems will be fixed soon.
    
    We recommend that you upgrade your Linux kernel packages immediately.
