                    Mandrake Linux Security Update Advisory
    ________________________________________________________________________

    Package name: kernel
    Advisory ID: MDKSA-2003:066-2
    Date: July 25th, 2003
    Original Advisory Date: June 11th, 2003
    Affected versions: 9.1
    ________________________________________________________________________

    Problem Description:

     Multiple vulnerabilities were discovered and fixed in the Linux kernel.
     
     * CAN-2003-0001: Multiple ethernet network card drivers do not pad
       frames with null bytes which allows remote attackers to obtain
       information from previous packets or kernel memory by using
       special malformed packets.
     
     * CAN-2003-0244: The route cache implementation in the 2.4 kernel and
       the Netfilter IP conntrack module allows remote attackers to cause a
       Denial of Service (DoS) via CPU consumption due to packets with
       forged source addresses that cause a large number of hash table
       collisions related to the PREROUTING chain.
     
     * CAN-2003-0246: The ioperm implementation in 2.4.20 and earlier
       kernels 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 2.4 kernel
       allows attackers to cause a kernel oops resulting in a DoS.
     
     * CAN-2003-0248: The mxcsr code in the 2.4 kernel allows attackers to
       modify CPU state registers via a malformed address.
     
     * CAN-2003-0462: A file read race existed in the execve() system call.
     
     As well, a number of bug fixes were made in the 9.1 kernel including:
     
     * Support for more machines that did not work with APIC
     * Audigy2 support
     * New/updated modules: prims25, adiusbadsl, thinkpad, ieee1394,
       orinoco, via-rhine,
     * Fixed SiS IOAPIC
     * IRQ balancing has been fixed for SMP
     * Updates to ext3
     * The previous ptrace fix has been redone to work better
     * Bugs with compiling kernels using xconfig have been fixed
     * Problems with ipsec have been corrected
     * XFS ACLs are now present
     * gdb not working on XFS root filesystems has been fixed
     
     MandrakeSoft encourages all users to upgrade to these new kernels.
     Updated kernels will be available shortly for other supported platforms
     and architectures.
     
     For full instructions on how to properly upgrade your kernel, please
     review http://www.mandrakesecure.net/en/docs/magic.php.
      
    Update:

     The kernels provided in MDKSA-2003:066-1 (2.4.21-0.24mdk) had a problem
     where all files created on any filesystem other than XFS, and using any
     kernel other than kernel-secure, would be created with mode 0666, or
     world writeable. The 0.24mdk kernels have been removed from the
     mirrors and users are encouraged to upgrade and remove those kernels
     from their systems to prevent accidentally booting into them.
     
     That issue has been addressed and fixed with these new kernels.
