    Package        : logcheck
    Vulnerability  : insecure temporary directory
    Problem-Type   : local
    Debian-specific: no
    CVE Ids        : CAN-2004-0404
    Christian Jaeger reported a bug in logcheck which could potentially be
    exploited by a local user to overwrite files with root privileges.
    logcheck utilized a temporary directory under /var/tmp without taking
    security precautions.  While this directory is created when logcheck
    is installed, and while it exists there is no vulnerability, if at
    any time this directory is removed, the potential for exploitation exists.
    For the current stable distribution (woody) this problem has been
    fixed in version 1.1.1-13.1woody1.
    For the unstable distribution (sid), this problem has been fixed in
    version 1.1.1-13.2.
    We recommend that you update your logcheck package.
