You are passing parameters. For instance, when you invoke a media player
through shell:xxx.mp3, the filename xxx.mp3 is the parameter.

The advisory mentions that combining this with a BoF can result in
remote code execution, but they totally forget to mention that formatstring
exploits, integeroverflows, XSS, SQL injection, etc... might cause the same
problems too. I bet they just read FD and didn't think for themselves. As
far as I can see, this bug allows an attacker to remotely abuse any
vulnerability a local program might be subject to, thus making any local
exploit a possible remote exploit.

It would seem that one would have to be able to pass
parameters to the file being called for these types of
attacks to be possible.
