    Tatsuya Kinoshita discovered that IM, which contains interface
    commands and Perl libraries for E-mail and NetNews, creates temporary
    files insecurely.
    
     1. 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.
    
     2. 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).
    
    We recommend that you upgrade your IM package.
    
    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.

      These files will probably be moved into the stable distribution on
      its next revision.
