The answer to how that program work are in the URL you linked.

The called program overwrites it's arguments after making a copy of them. But as one of the other comments adds, there's still a brief period of time when the commands arguments are visible so it's not foolproof.

The only way to make sure information you want to remain private isn't exposed as a command argument is to either encrypt it first, or to have the calling and called program communicate the info some other way. You could use a file, shared memory, IPC, a pipe, etc...

glgetattriblocation

GLGETATTRIBLOCATION(3G) 					  [FIXME: manual]					   GLGETATTRIBLOCATION(3G)

NAME

       glGetAttribLocation - Returns the location of an attribute variable

C SPECIFICATION

       GLint glGetAttribLocation(GLuint program, const GLchar *name);

PARAMETERS

       program
	   Specifies the program object to be queried.

       name
	   Points to a null terminated string containing the name of the attribute variable whose location is to be queried.

DESCRIPTION

       glGetAttribLocation queries the previously linked program object specified by program for the attribute variable specified by name and
       returns the index of the generic vertex attribute that is bound to that attribute variable. If name is a matrix attribute variable, the
       index of the first column of the matrix is returned. If the named attribute variable is not an active attribute in the specified program
       object or if name starts with the reserved prefix "gl_", a value of -1 is returned.

       The association between an attribute variable name and a generic attribute index can be specified at any time by calling
       glBindAttribLocation(). Attribute bindings do not go into effect until glLinkProgram() is called. After a program object has been linked
       successfully, the index values for attribute variables remain fixed until the next link command occurs. The attribute values can only be
       queried after a link if the link was successful.  glGetAttribLocation returns the binding that actually went into effect the last time
       glLinkProgram() was called for the specified program object. Attribute bindings that have been specified since the last link operation are
       not returned by glGetAttribLocation.

ERRORS

       GL_INVALID_OPERATION is generated if program is not a value generated by OpenGL.

       GL_INVALID_OPERATION is generated if program is not a program object.

       GL_INVALID_OPERATION is generated if program has not been successfully linked.

ASSOCIATED GETS

       glGetActiveAttrib() with argument program and the index of an active attribute

       glIsProgram()
