Re: [X2Go-Dev] setuid/setgid in libXcomp

Hey,

this is a bit of guesswork, but,

• getgit get the _real_ real gid
• setgit sets the _effective_ gid Thus you reset the effective s/gid.

Can anyone explain to my why libXcomp calls setgid/setuid in Pipe.cpp:Popen() after calling fork()? It also isn't checking the results of the call, but I'm really not sure why the calls are there in the first place.

switch (pid = Fork()) { ... case 0: { // // Child. //

  setgid(getgid());
  setuid(getuid());

Nothing is running as a setuid/setgid process is it?
