    Package : cfengine
    Vulnerability : insecure temporary files
    Problem type : local
    Debian-specific: no
    CVE ID : CAN-2005-2960

    Javier Fernández-Sanguino Peña discovered several insecure temporary
    file uses in cfengine, a tool for configuring and maintaining
    networked machines, that can be exploited by a symlink attack to
    overwrite arbitrary files owned by the user executing cfengine, which
    is probably root.

    For the old stable distribution (woody) these problems have been fixed in
    version 1.6.3-9woody1.

    For the stable distribution (sarge) these problems have been fixed in
    version 1.6.5-1sarge1.

    For the unstable distribution (sid) these problems have will be fixed soon.

    We recommend that you upgrade your cfengine 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
    apt-get upgrade
            will install corrected packages

    You may use an automated update by adding the resources from the
    footer to the proper configuration.
