I wouldn't use a program B to circumvent a bug of another program A if not in a exceptional case in which patch of program A cannot be created.

This is exactly the case. If bash has a bug. that must be fixed. And it has been done already. Just update bash in major distributions and the bug is gone.

But still you want to have a tool like sysdig to detect if your system has already been compromised previously and it is out of sysadmin control.
