    Package        : kdenetwork
    Vulnerability  : buffer overflow
    Problem-Type   : local
    Debian-specific: no
    CVE Id         : CAN-2002-1247
    iDEFENSE reports a security vulnerability in the klisa package, that
    provides a LAN information service similar to "Network Neighbourhood",
    which was discovered by Texonet.  It is possible for a local attacker
    to exploit a buffer overflow condition in resLISa, a restricted
    version of KLISa.  The vulnerability exists in the parsing of the
    LOGNAME environment variable, an overly long value will overwrite the
    instruction pointer thereby allowing an attacker to seize control of
    the executable.
    This problem has been fixed in version 2.2.2-14.2 the current stable
    distribution (woody) and in version 2.2.2-14.3 for the unstable
    distribution (sid).  The old stable distribution (potato) is not
    affected since it doesn't contain a kdenetwork package
    We recommend that you upgrade your klisa package immediately.
    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.

      Please note that the source packages mentioned above produce more
      binary packages than the ones listed above.  They are not relevant
      for the fixed problems, though.
      These files will probably be moved into the stable distribution on
      its next revision.
