How do check the programs that the actual user of the computer installed. I do not care at all about the default programs that came with your distro of Linux, I only want the user installed programs. (1 Reply)

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?

elksemu
elksemu(1) General Commands Manual elksemu(1)NAME
elksemu - Embedded Linux Kernel Subset emulator
SYNOPSIS
/lib/elksemu program [arguments]
DESCRIPTION
Elksemu is a program that allows 8086 ELKS programs to be run under Linux-i386. These programs can be compiled using the bcc(1) C compiler.
It is not usual to invoke /lib/elksemu directly, either the simple patch or kernel module distributed with it will cause the kernel to run
/lib/elksemu with the correct arguments whenever the user tries to execute an ELKS executable directly.
OPTIONS
There are no flag options to elksemu, the first argument is the name of the program to run the rest are arguments that are passed to the
Elks program.
The elksemu program is normally installed suid-root and in this event it is able to run execute only (chmod 111) elks executables and act
correctly on the suid permission bits on those executable. This may be considered a security hazard so elksemu does not have to be
installed suid-root.
SEE ALSO bcc(1), as86(1), ld86(1)BUGS
Elksemu is incomplete.
The program may still have security bugs!
