Descriptions

object-observe.js in Google V8, as used in Google Chrome before 45.0.2454.101, does not properly restrict method calls on access-checked objects, which allows remote attackers to bypass the Same Origin Policy via a (1) observe or (2) getNotifier call.

object-observe.js en Google V8, tal como se utiliza en Google Chrome en versiones anteriores a 45.0.2454.101, no restringe adecuadamente las llamadas a métodos en objetos de acceso verificado, lo que permite a atacantes remotos eludir la Same Origin Policy a través de una llamada (1) observe o (2) getNotifier .

Chromium is an open-source web browser, powered by WebKit. Two flaws were found in the processing of malformed web content. A web page containing malicious content could cause Chromium to bypass cross origin restrictions, and access or modify data from an unrelated web site. All Chromium users should upgrade to these updated packages, which contain Chromium version 45.0.2454.101, which corrects these issues. After installing the update, Chromium must be restarted for the changes to take effect.
