x86_64 Intel(R) Core(TM) i5-2540M CPU @ 2.60GHz GenuineIntel GNU/Linux
Machine Type: x86_64-pc-linux-gnu
Bash Version: 4.3
Patch Level: 33
Release Status: release
Description:
It is possible to supply many ascii control characters as function
names. This allows obfuscation of function calls because the majority of
these are non printing characters.
https://github.com/airencracken/why/blob/master/control_character_functions.sh
Repeat-By:
Define a function with a control character, then call it.
Fix:
Disallow functions to be named after control characters or non-printing
characters in general.
