See that one with the very strange name?
The one whose filename looks like a shell command?
Guess what, it is.
What in the *nix world is called a: "poison filename".

The most recent versions of the series 5.x firmware goes through a filename check and rename process that avoids letting the shell actually execute the filename.[quote]
A poison filename, cool.
I have always read about hacking tecniques - though not specific to kindle - and always wondered how one could discover them... poison filenames, stack overflows
Just playing around ramdomly? In this case, creating filenames at random?

Quote:
Which is actually more convoluted than the system built-in method of avoiding poison filenames - but we have stopped giving Lab126 Linux lessons.
You mean there's some modification in the linux kernel the Kindle uses that checks for filenames not being... don't know, longer than a set length, before executing them?
