    Package        : sysstat
    Vulnerability  : insecure temporary file
    Problem-Type   : local
    Debian-specific: no
    CVE Ids        : CAN-2004-0108
    Alan Cox discovered that the isag utility (which graphically displays
    data collected by the sysstat tools), creates a temporary file without
    taking proper precautions.  This vulnerability could allow a local
    attacker to overwrite files with the privileges of the user invoking
    For the current stable distribution (woody) this problem has been
    fixed in version 5.0.1-1.
    For the unstable distribution (sid) this problem will be fixed soon.
    We recommend that you update your sysstat package.
    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
