i missed out that

solaris 5.9

the issue is just not displaying the dynamic dependencies...
as ldd is not able to list them all with the s-bit set for the binary...

naturally am not able to run the binary also,
ld.so.1 linker fails to locate the necessary libs

the issue is ---> "without s-bit it works perfect.. when s-bit is set that it crashes"

on a truss for that binary.. there is a pipe error from ld.so.1 as displayed by the system call tracer

i dont know how using the other options of ldd would help me to locate the dependencies of the binary for which s-bit is set...

hope i have made my problem clear...

What keeps me from abusing setuid(0) and programs with setuid bit set?

Just learning about the privilege escalation method provided by setuid. Correct me if I am wrong but what it does is change the uid of the current process to whatever uid I set. Right ? So what stops me from writing my own C program and calling setuid(0) within it and gaining root privileges ? ... (2 Replies)

NAME
ldd - print shared library dependencies SYNOPSIS
ldd [OPTION]... FILE... DESCRIPTION
ldd prints the shared libraries required by each program or shared library specified on the command line. OPTIONS
--version Print the version number of ldd. -v --verbose Print all information, including e.g. symbol versioning information. -d --data-relocs Perform relocations and report any missing objects (ELF only). -r --function-relocs Perform relocations for both data objects and functions, and report any missing objects or functions (ELF only). -u --unused Print unused direct dependencies. --help Usage information. BUGS
ldd does not work on a.out shared libraries. ldd does not work with some extremely old a.out programs which were built before ldd support was added to the compiler releases. If you use ldd on one of these programs, the program will attempt to run with argc = 0 and the results will be unpredictable. AUTHOR
