## Command format-string-helper ##

The `format-string-helper` command will create a `GEF` specific type of
breakpoints dedicated to detecting potentially insecure format string when
using the GlibC library.

It will use this new breakpoint against several targets, including:

   * `printf()`
   * `sprintf()`
   * `fprintf()`
   * `snprintf()`
   * `vsnprintf()`

Just call the command to enable this functionality. `fmtstr-helper` is an alias of `format-string-helper`.
```
gef➤ fmtstr-helper
```

Then start the binary execution.
```
gef➤ g
```

If a potentially insecure entry is found, the breakpoint will trigger, stop the
process execution, display the reason for trigger and the associated context.
