Une version corrective de Firefox 97.0.2 et 91.6.1 est disponible, corrigeant deux vuln\u00e9rabilit\u00e9s class\u00e9es comme probl\u00e8mes critiques. Ces vuln\u00e9rabilit\u00e9s permettent de contourner l'isolation sandbox et d'ex\u00e9cuter du code malveillant avec des privil\u00e8ges de navigateur lors du traitement de contenu sp\u00e9cialement con\u00e7u. Il a \u00e9t\u00e9 signal\u00e9 que des exploits fonctionnels existent pour les deux probl\u00e8mes, qui sont d\u00e9j\u00e0 utilis\u00e9s pour mener des attaques. <\/p>\n

Les d\u00e9tails restent encore \u00e0 \u00eatre divulgu\u00e9s, il n'est connu que la premi\u00e8re vuln\u00e9rabilit\u00e9 (CVE-2022-26485) est li\u00e9e \u00e0 un acc\u00e8s \u00e0 une zone de m\u00e9moire d\u00e9j\u00e0 lib\u00e9r\u00e9e (Use-after-free) dans le code de gestion du param\u00e8tre XSLT, tandis que la seconde (CVE-2022-26486) concerne l'acc\u00e8s \u00e0 de la m\u00e9moire d\u00e9j\u00e0 lib\u00e9r\u00e9e dans le framework IPC de WebGPU. <\/p>\n

Tous les utilisateurs des navigateurs bas\u00e9s sur Firefox sont fortement invit\u00e9s \u00e0 mettre \u00e0 jour imm\u00e9diatement. Les utilisateurs de Tor Browser, qui est bas\u00e9 sur la branche ESR de Firefox 91, doivent \u00eatre particuli\u00e8rement attentifs lors de l'installation des mises \u00e0 jour, car les vuln\u00e9rabilit\u00e9s peuvent non seulement compromettre le syst\u00e8me, mais aussi d\u00e9-anonymiser l'utilisateur. La mise \u00e0 jour corrigeant ces vuln\u00e9rabilit\u00e9s pour Tor Browser n'est pas encore disponible.
