    Package        : cfengine2
    Vulnerability  : insecure temporary files
    Problem type   : local
    Debian-specific: no
    CVE ID         : CAN-2005-2960
    Javier Fernández-Sanguino Peña discovered insecure temporary file use
    in cfengine2, 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.
    The old stable distribution (woody) is not affected by this problem.
    For the stable distribution (sarge) these problems have been fixed in
    version 2.1.14-1sarge1.
    For the unstable distribution (sid) these problems will be fixed soon.
    We recommend that you upgrade your cfengine2 package.
