    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:
        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
        A vulnerability has been discovered in the R128 drive in the Linux
        kernel which could potentially lead an attacker to gain
        unauthorised privileges.  Alan Cox and Thomas Biege developed a
        correction for this
        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.
        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.
        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.
        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.
    Architecture      stable (woody)            unstable (sid)
    source            2.4.16-1woody2            2.4.25-3
    arm/patch         20040419                  20040316
    arm/lart          20040419                  2.4.25-4
    arm/netwinder     20040419                  2.4.25-4
    arm/riscpc        20040419                  2.4.25-4
    We recommend that you upgrade your kernel packages immediately, either
    with a Debian provided kernel or with a self compiled one.
    Upgrade Instructions
    - --------------------
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
    If you are using the apt-get package manager, use the line for
    sources.list as given below:
    apt-get update
            will update the internal database
    apt-get upgrade
            will install corrected packages
    You may use an automated update by adding the resources from the
    footer to the proper configuration.

      These files will probably be moved into the stable distribution on
      its next revision.
