The patch I used can be found on: http://people.debian.org/~nion/nmu-diff/netatalk-2.0.3-11_2.0.3-11+lenny1.patchI am not very happy with the patch because it just filters a handful of characters, a better solution would be to replace popen(). (I mentioned this on the netatalk-devel ML but got no answer so far.)
It is no full shell escape but escapes everything that should be relevant for command injection. Sure, replacing the popen would be the better option but I was not too happy doing this as I guess it's more likely to break existing functionality with it by accident.
