    Package        : wmtv
    Vulnerability  : symlink vulnerability
    Problem-Type   : local
    Debian-specific: no
    
    Nicolas Boullis found some security problems in the wmtv package (a
    dockable video4linux TV player for windowmaker) which is distributed
    in Debian GNU/Linux 2.2.  With the current version of wmtv, the
    configuration file is written back as the superuser, and without any
    further checks.  A mailicious user might use that to damage important
    files
    
    This problem has been fixed in version 0.6.5-2potato2 for the stable
    distribution by dropping privileges as soon as possible and only
    regaining them where required.  In the current testing/unstable
    distribution this problem has been fixed in version 0.6.5-9 and above
    by not requiring privileges anymore.  Both contain fixes for two
    potential buffer overflows as well.
    
    We recommend that you upgrade your wmtv packages 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.

      These files will probably be moved into the stable distribution on
