SetUID and SetGID question

[Ioannis Vranos]

Hi,

I am confused regarding SetUID and SetGID flags of executables.

More specifically, what is the use of enabling them *both*, since when
the executable is run, it is run with owner's privileges because of
SetUID?

I mean enabling them both, doesn't have the same effect, as enabling
SetUID only?



Thank you,
