given a welcome binary that don't have exec flag on it

and a wrapper binary that has setuid (user that can read the flag.txt file )

The idea was to execute welcome binary using the linker "/lib/ld*.so" as ELF interpreter

so running the wrapper binary then just

```
/lib64/ld-linux-x86-64.so.2 ./welcome
```

will print the flag
