    Package        : wmtv
    Problem type   : local root exploit
    Debian-specific: no
    Nicolas Boullis found a nasty security problem in the wmtv (a
    dockable video4linux tv player for windowmaker) package as
    distributed in Debian GNU/Linux 2.2.
    wmtv can optionally run a command if you double-click on the tv
    window. This command can be specified using the -e command-line
    option. However since wmtv is installed suid root this command
    was also run as root, which gives local users a very simple way
    to get root access.
    This has been fixed in version 0.6.5-2potato1 by dropping root
    privileges before executing the command. We recommend that you
    upgrade your wmtv package immediately.
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
