The name canary comes from how the birds were historically used in coal mines. Coal mines did not always have breathable air, and, if it was not for canaries, coal miners would be subject to methane, carbon monoxide, and even explosions. By sending canaries into coal mines first, and observing whether the canaries died, coal miners could determine if it was safe for them to enter. In a similar fashion, by placing a canary value just before the return address, a program can look at the canary value to determine if it is safe to jump to the return address. If some potentially malicious user input overwrote and corrupted the canary, it would clearly not be safe to jump to the return address. pdf417 java QuaggaJS, an advanced barcode-reader written in JavaScript

Although making certain controller actions private prevents any user from accessing a method, you will often need to restrict access to just certain users. You can do this by using Pylons __before__() method and session functionality. Create a new controller for the AuthTest project called homegrown: $ paster controller homegrown You ll recall that on each request the __before__() method of the controller is called before the controller action is called. Let s set up a simple session variable named user that will be used to store the username of the authenticated user. If the user session variable isn t set, you can assume no user is signed in. If it is set, you can set the REMOTE_USER environment variable. class HomegrownController(BaseController): def __before__(self, action, **params): user = session.get('user') if user: request.environ['REMOTE_USER'] = user def signin(self): if len(request.params) > 1 and \ request.params['password'] == request.params['username']: session['user'] = request.params['username'] session.save() return redirect_to(controller='homegrown', action="private") else: return """\ <html> <head><title>Please Login!</title></head> <body> <h1>Please Login</h1> <form action="signin" method="post"> add image to existing pdf using itextsharp c#, vb.net ean 13 reader, formule ean13 excel, generate code 39 barcode in c#, c# qr code reader, split pdf using c# pdf417 scanner javascript Java Barcode API - DZone Java

If you enter a username that is the same as the password, you will be shown the private message. You will be able to continue to see the private message until you clear the Pylons session cookie by closing your browser. This example works perfectly well for the straightforward case described earlier, but when you start dealing with complex permissions and different authentication methods, it quickly becomes preferable to use an authentication and authorization framework. pdf417 java open source Java PDF-417 Reader Library to read, scan PDF-417 barcode ...

The StackGuard canary approach only works, of course, if the attacker cannot predict what the canary will be. If the canary were a fixed value, the attacker could simply rewrite the fixed value, and follow it by the return address of his choice. Instead, the canary value is chosen to be a random value, unpredictable to an attacker. If the canary has been modified, then it means that an attacker might be trying to overflow a buffer. In response to a corrupt canary, the code could halt the program to prevent an attacker from gaining control of the program. While StackGuard-type approaches help deal with some types of buffer overflow attacks, the protection they offer is not comprehensive. For more details, see Bypassing StackGuard and StackShield, by Bulba and Kil3r. pdf417 java decoder zxing-js/library: Multi-format 1D/2D barcode image ... - GitHub
