<p>The nihilant: /* Inscriptions */</p> <hr /> <div>Vous aimeriez en savoir plus sur l’exploitation de vulnérabilités kernel, voir à quoi ces failles ressemblent dans le code, et surtout comment les exploiter ?<br /> <br /> == Quoi ==<br /> <br /> Je vous propose de passer la journée à analyser une vulnérabilité assez récente affectant le kernel Linux, à savoir le [https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2013-1763 CVE-2013-1763]. Cette vulnérabilité permet d’élever ses privilèges d’un compte utilisateur vers le compte root. Durant l'atelier nous expliquerons le fonctionnement de la faille et essayerons d’écrire l’exploit correspondant.<br /> <br /> == Qui ==<br /> <br /> * Par [[User:Corentin|Corentin]]<br /> * Pour 5 à 15 personnes.<br /> <br /> == Où et quand ==<br /> <br /> À [[la Gare XP]], le '''Samedi 6 Avril 2013''', à '''14h'''. Pendant 2h à 4h selon. Une seule session prévue.<br /> <br /> == Prérequis ==<br /> <br /> * Savoir développer en C<br /> * Savoir compiler un kernel Linux<br /> * Un laptop avec QEMU/KVM, ou VMware, ou VirtualBox déjà installé<br /> * Une VM Linux avec un kernel &gt;= 3.3 le tout en 64 bit (si vous utilisez QEMU/KVM je pourrai fournir la VM et le kernel).<br /> * Au besoin il faut ré-introduire [http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=6e601a53566d84e1ffd25e7b6fe0b6894ffd79c0 le bug] dans le code avant de compiler le kernel.<br /> * Si vous êtes joueur vous pouvez utiliser un système 32-bit, cependant cette vulnérabilité est beaucoup plus facilement exploitable en 64-bit.<br /> <br /> == Inscriptions ==<br /> <br /> Pour participer, inscris-toi ici:<br /> * [[User:Capslock|CapsLock]]<br /> * the_nihilant<br /> * Pseudo2<br /> * etc...<br /> <br /> [[Category:Workshops]]</div>
