    Package        : nis
    Vulnerability  : information leak
    Problem-Type   : remote
    Debian-specific: no
    
    Thorsten Kukuck discovered a problem in the ypserv program which is
    part of the Network Information Services (NIS).  A memory leak in all
    versions of ypserv prior to 2.5 is remotely exploitable.  When a
    malicious user could request a non-existing map the server will leak
    parts of an old domainname and mapname.
    
    This problem has been fixed in version 3.9-6.1 for the current stable
    distribution (woody), in version 3.8-2.1 for the old stable
    distribution (potato) and in version 3.9-6.2 for the unstable
    distribution (sid).
    
    We recommend that you upgrade your nis 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.
