Setuid root and chown

I am trying to run chown and chmod from a script owned by root. The permissions are set to 4755 so that users can execute the script as root. However, when I run the script as a user other than root, I get "Operation not permitted" for both chown and chmod. Any ideas as to why this is?

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.

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 ? ...

CURLOPT_PROXY_SSL_OPTIONS(3)				     curl_easy_setopt options				      CURLOPT_PROXY_SSL_OPTIONS(3)

NAME

       CURLOPT_PROXY_SSL_OPTIONS - set proxy SSL behavior options

SYNOPSIS

       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSL_OPTIONS, long bitmask);

DESCRIPTION

       Pass a long with a bitmask to tell libcurl about specific SSL behaviors.

       CURLSSLOPT_ALLOW_BEAST  tells  libcurl to not attempt to use any workarounds for a security flaw in the SSL3 and TLS1.0 protocols.  If this
       option isn't used or this bit is set to 0, the SSL layer libcurl uses may use a work-around for this flaw although it might cause  interop-
       erability  problems  with  some	(older)  SSL implementations. WARNING: avoiding this work-around lessens the security, and by setting this
       option to 1 you ask for exactly that.  This option is only supported for DarwinSSL, NSS and OpenSSL.

       CURLSSLOPT_NO_REVOKE tells libcurl to disable certificate revocation checks for those SSL backends where such  behavior	is  present.  Cur-
       rently  this option is only supported for WinSSL (the native Windows SSL library), with an exception in the case of Windows' Untrusted Pub-
       lishers blacklist which it seems can't be bypassed. This option may have broader support to accommodate other SSL backends in  the  future.
