"Tatsuya Kinoshita discovered that IM, which contains interface
commands and Perl libraries for E-mail and NetNews, creates temporary
files insecurely.

  - The impwagent program creates a temporary directory in
    an insecure manner in /tmp using predictable directory
    names without checking the return code of mkdir, so it's
    possible to seize a permission of the temporary
    directory by local access as another user.
  - The immknmz program creates a temporary file in an
    insecure manner in /tmp using a predictable filename, so
    an attacker with local access can easily create and
    overwrite files as another user.

These problems have been fixed in version 141-18.1 for the current
stable distribution (woody), in version 133-2.2 of the old stable
distribution (potato) and in version 141-20 for the unstable
distribution (sid)."
