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.


Debian GNU/Linux 2.2 alias potato
