    Package : kernel-patch-2.4.17-mips
    Vulnerability : integer overflow
    Problem-Type : local
    Debian-specific: no
    CVE ID : CAN-2003-0961

    RedHat and SuSE kernel and security teams revealed an integer overflow
    in the do_brk() function of the Linux kernel allows local users to
    gain root privileges.

    For the stable distribution (woody) this problem has been fixed in
    version 2.4.17-0.020226.2.woody4. Other architectures are already or
    will be fixed separately.

    For the unstable distribution (sid) this problem will be fixed soon
    with newly uploaded packages.

    We recommend that you upgrade your kernel image packages for the mips
    and mipsel architectures. This problem has been fixed in the upstream
    version 2.4.23 as well and is also present in 2.4.24, of course.

    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.
