STATUS_STACK_BUFFER_OVERRUN a rencontré VS 2015

Question

Après la réécriture du code (application de formulaires Windows) de VS 2005 à VS 2015, une erreur "STATUS_STACK_BUFFER_OVERRUN a été détectée" se produit. Dans le programme VS2005 fonctionne très bien. Je ne sais pas vraiment ce qui ne va pas. Le code a été écrit dans XP OS. Maintenant, je suis en train de le démarrer sur win7 64 bits VS2015. Ce programme est un exemple de ma classe de programmation. Besoin de le réutiliser à d'autres fins.

Answer 1

int sinus_tab[345]; 
    while (i <= 345) { 
     sinus_tab[i] = 80 - Convert::ToInt32(y0); // tablica elementów sinusa 
    } 

Mise en évidence les lignes de code qui provoquent cette erreur d'exécution. Vous avez un bug hors-un dans votre code. Le dernier index valide dans sinus_tab [] est 344. Mais vous écrivez sinus_tab [345], la condition while-loop devrait probablement être i < 345. C'est un bug de débordement de tampon, il corrompt aléatoirement le cadre de la pile. Ce type de corruption de la mémoire peut ne pas être détecté.

Vous avez exactement le même bug dans troj_tab [].

Les bugs de débordement de tampon comme celui-ci sont un vecteur d'attaque de virus notoire, il permet de manipuler le programme avec des données. Dans ce cas particulier, vous n'avez vu aucun effet néfaste, mais vous pourriez par exemple écraser l'adresse de retour. Faire sauter le programme à un emplacement arbitraire.

Microsoft a mis en place des contre-mesures pour arrêter ce type d'attaques depuis .NET 4.0 (VS2010). Votre bug déclenche ce mécanisme de détection de dépassement de tampon, il écrase le canari de la pile et votre programme s'interrompt correctement.

Utilisez un tableau géré à la place afin que vous puissiez détecter les bogues comme ceci tôt, vous obtenez une exception IndexOutOfRangeException. Correction:

array<int>^ sinus_tab = gcnew array<int>(345);
