Une vuln\u00e9rabilit\u00e9 a \u00e9t\u00e9 d\u00e9tect\u00e9e dans le syst\u00e8me de blocage de contenu ind\u00e9sirable uBlock Origin, permettant de provoquer un crash ou une exhaustion de m\u00e9moire lors de la navigation sur une URL sp\u00e9cialement con\u00e7ue, si cette URL est soumise aux filtres de blocage stricts (\u00ab strict blocking \u00bb). La vuln\u00e9rabilit\u00e9 se manifeste uniquement lors d'un acc\u00e8s direct \u00e0 l'URL probl\u00e9matique, par exemple en cliquant sur un lien. <\/p>\n

La vuln\u00e9rabilit\u00e9 a \u00e9t\u00e9 corrig\u00e9e dans la mise \u00e0 jour uBlock Origin 1.36.2. Un probl\u00e8me similaire affecte \u00e9galement l'extension uMatrix, mais son support a \u00e9t\u00e9 interrompu et aucune mise \u00e0 jour n'est plus publi\u00e9e. Il n'existe pas de solutions de contournement s\u00e9curis\u00e9es dans uMatrix (il avait \u00e9t\u00e9 initialement sugg\u00e9r\u00e9 de d\u00e9sactiver tous les filtres de blocage strict via l'onglet \u00ab Assets \u00bb, mais cette recommandation a \u00e9t\u00e9 jug\u00e9e insuffisante et probl\u00e9matique pour les utilisateurs ayant leurs propres r\u00e8gles de blocage). Dans uMatrix, un fork d'uMatrix issu du projet Pale Moon, la vuln\u00e9rabilit\u00e9 a \u00e9t\u00e9 r\u00e9solue dans la version 4.4.9. <\/p>\n

Le filtre de blocage strict est g\u00e9n\u00e9ralement d\u00e9fini au niveau domaines<\/a> et implique l'interdiction de toute connexion, m\u00eame lors d'un acc\u00e8s direct via un lien. La vuln\u00e9rabilit\u00e9 est caus\u00e9e par le fait qu'en acc\u00e9dant \u00e0 une page soumise \u00e0 un filtre de blocage strict, un avertissement s'affiche \u00e0 l'utilisateur, fournissant des informations sur la ressource bloqu\u00e9e, y compris l'URL et les param\u00e8tres de la requ\u00eate. Le probl\u00e8me r\u00e9side dans le fait que uBlock Origin analyse les param\u00e8tres de la requ\u00eate de mani\u00e8re r\u00e9cursive et les ajoute \u00e0 l'arbre DOM sans tenir compte du niveau d'imbrication. <\/p>\n

Lors du traitement d'une URL sp\u00e9cialement con\u00e7ue dans uBlock Origin pour Chrome, il est possible de provoquer le plantage du processus ex\u00e9cutant l'extension du navigateur. Apr\u00e8s le plantage, tant que le processus avec l'extension n'est pas red\u00e9marr\u00e9, l'utilisateur reste sans blocage de contenu ind\u00e9sirable. Dans Firefox, un \u00e9puisement de la m\u00e9moire a \u00e9t\u00e9 observ\u00e9.
