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.
