"Jens Steube discovered several vulnerabilities in remstats, the remote
statistics system. The Common Vulnerabilities and Exposures project
identifies the following problems :

  - CAN-2005-0387
    When processing uptime data on the unix-server a
    temporary file is opened in an insecure fashion which
    could be used for a symlink attack to create or
    overwrite arbitrary files with the permissions of the
    remstats user.

  - CAN-2005-0388

    The remoteping service can be exploited to execute
    arbitrary commands due to missing input sanitising."
