Can you gain root privileges if the suid program does not belong to root?

I had a question in my test which asked where suppose user B has a program with 's' bit set. Can user A run this program and gain root privileges in any way? I suppose not as the suid program run with privileges of owner and this program will run with B's privileges and not root. (1 Reply)

NAME
fdutilsconfig - configure the suid bit of fdmount SYNOPSIS
fdutilsconfig DESCRIPTION
The fdutilsconfig script provides an interactive way to configure the suid bit of the fdmount(1) binary. It asks you some questions, give you a hint if needed, and enters your choice to /etc/fdmount.conf file. When upgrading the Debian fdutils package, the suid bit information stored in /etc/fdmount.conf is used to tell the new fdmount binary to keep your old suid bit settings. The script makes use of the suidmanager Debian package, if it is installed. If the script cannot find it, it manipulates the suid bit directly via `chmod u+s' command. FILES
fdutilsconfig reads and writes the configuration from /etc/fdmount.conf. This file is usually created when the fdutils package is installed for the first time. Please don't edit /etc/fdmount.conf manually! Use fdutilsconfig instead. NOTE
This script was written exclusively for the Debian GNU/Linux distribution. It is not a part of the upstream fdutils sources. AUTHORS
fdutilsconfig was adapted by Anthony Fok <foka@debian.org> from the gnuplotconfig script written by Tibor Simko <simko@debian.org>. SEE ALSO
