Greetings. For those of us still in our admin swaddling, could someone
explain the practical implications of this (from the security README):

>This solution will default to making the stack of all suid programs to be
>not executable, hence closing the security hole. However, please be aware
>that any user applications which rely on the stack being executable will
>fail. For situations where the machines are being used behind firewalls

Generally, do apps need an executable stack to work, and when
might an app need an executable stack? Specifically, will general SUID
apps still work? Any specific apps that you know will have problems?


thanks and cheers,
