>Description:
gtk2-theme-switch does not check the return value of the fopen()
call in ok_clicked(), line 210 inside switch.c. For some reason,
I had some strange permissions on the ~/gtkrc-2.0 file that it
attempted to open and write to. The call failed and an invalid
pointer was passed to fprintf, causing a crash.
>How-To-Repeat:
$ chmod 000 ~/.gtkrc-2.0
$ gtk2-theme-switch
(click 'apply')
crash!
>Fix:
A simple fix would be to check the return value of the fopen()
call and display some sort of error. I don't know the gtk toolkit
well enough to do this though.
There are a quite a few unchecked fopen() calls in this program.
Be warned!
