"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
