Les d\u00e9veloppeurs de Mozilla ont publi\u00e9 de nouvelles versions des navigateurs web Firefox 74.0.1 et Firefox ESR 68.6.1. Il est recommand\u00e9 aux utilisateurs de mettre \u00e0 jour leurs navigateurs, car les nouvelles versions corrigent deux vuln\u00e9rabilit\u00e9s de type zero-day qui sont exploit\u00e9es par des hackers en pratique.<\/p>\n

\"Deux<\/p>\n

Il s'agit des vuln\u00e9rabilit\u00e9s CVE-2020-6819 et CVE-2020-6820, li\u00e9es \u00e0 la gestion de l'espace m\u00e9moire par Firefox. Ce sont des vuln\u00e9rabilit\u00e9s d'utilisation de m\u00e9moire apr\u00e8s lib\u00e9ration qui permettent aux hackers d'injecter du code arbitraire dans la m\u00e9moire de Firefox pour ex\u00e9cuter ce code dans le contexte du navigateur. Ces vuln\u00e9rabilit\u00e9s peuvent \u00eatre utilis\u00e9es pour une ex\u00e9cution de code \u00e0 distance sur les appareils des victimes.<\/p>\n

Les d\u00e9tails concernant les attaques r\u00e9elles utilisant les vuln\u00e9rabilit\u00e9s mentionn\u00e9es ne sont pas divulgu\u00e9s, ce qui est une pratique courante parmi les fournisseurs de logiciels et les chercheurs en s\u00e9curit\u00e9 informatique. Cela est d\u00fb au fait qu'ils se concentrent g\u00e9n\u00e9ralement sur la r\u00e9solution rapide des probl\u00e8mes d\u00e9tect\u00e9s et la livraison des correctifs aux utilisateurs, apr\u00e8s quoi une enqu\u00eate plus approfondie sur les attaques est men\u00e9e.<\/p>\n

Selon les informations disponibles, Mozilla enqu\u00eatera sur les attaques exploitant ces vuln\u00e9rabilit\u00e9s avec la soci\u00e9t\u00e9 de s\u00e9curit\u00e9 informatique JMP Security et le chercheur Francisco Alonso, qui a d\u00e9couvert le probl\u00e8me pour la premi\u00e8re fois. Le chercheur suppose que les vuln\u00e9rabilit\u00e9s corrig\u00e9es dans la derni\u00e8re mise \u00e0 jour de Firefox pourraient affecter d'autres navigateurs, bien qu'aucun cas d'exploitation des erreurs par des hackers dans diff\u00e9rents navigateurs web ne soit connu.<\/p>\n
