Package: bash Version: 4.2+dfsg-0.1+deb7u3 This command
$ b ash -c ' command_not_found_handle ( ) { echo this; } ; xxx'
allows you to run arbitrary code ('echo this') .
H ere 'xxx' must be the " name " of some non-existent command.
The following variant
$ b ash -c ' command_not_found_handle ( ) { xxx ; } ; xxx'
makes Bash enter in a loop , memory usage runaway from
control and the whole system hangs .
