La soci\u00e9t\u00e9 Google a publi\u00e9 la mise \u00e0 jour Chrome 93.0.4577.82, qui corrige 11 vuln\u00e9rabilit\u00e9s, dont deux probl\u00e8mes d\u00e9j\u00e0 exploit\u00e9s par des attaquants dans des exploits (0-day). Les d\u00e9tails ne sont pas encore divulgu\u00e9s, il est seulement connu que la premi\u00e8re vuln\u00e9rabilit\u00e9 (CVE-2021-30632) est caus\u00e9e par une erreur de d\u00e9passement de tampon dans le moteur JavaScript V8, et que le second probl\u00e8me (CVE-2021-30633) se trouve dans l'impl\u00e9mentation de l'API Indexed DB et est li\u00e9 \u00e0 l'acc\u00e8s \u00e0 la m\u00e9moire apr\u00e8s sa lib\u00e9ration (use-after-free). <\/p>\n

Parmi les autres vuln\u00e9rabilit\u00e9s : deux probl\u00e8mes caus\u00e9s par l'acc\u00e8s \u00e0 la m\u00e9moire apr\u00e8s sa lib\u00e9ration dans les API Selection et Permissions ; un traitement incorrect des types (Type Confusion) dans le moteur Blink ; et des d\u00e9bordements de tampon dans la couche ANGLE (Almost Native Graphics Layer Engine). Toutes les vuln\u00e9rabilit\u00e9s ont \u00e9t\u00e9 jug\u00e9es dangereuses. Aucune probl\u00e8me critique n'a \u00e9t\u00e9 d\u00e9tect\u00e9, permettant de contourner tous les niveaux de protection du navigateur et d'ex\u00e9cuter du code sur le syst\u00e8me en dehors de l'environnement sandbox.
