Updated chromium-browser-stable packages fix security vulnerabilities

Updated chromium-browser packages fix security vulnerabilities: Use-after-free vulnerability in the VisibleSelection::nonBoundaryShadowTreeRootNode function in core/editing/VisibleSelection.cpp in the DOM implementation in Blink, as used in Google Chrome before 40.0.2214.111 allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that triggers improper handling of a shadow-root anchor (CVE-2015-1209). The V8ThrowException::createDOMException function in bindings/core/v8/V8ThrowException.cpp in the V8 bindings in Blink, as used in Google Chrome before 40.0.2214.111 does not properly consider frame access restrictions during the throwing of an exception, which allows remote attackers to bypass the Same Origin Policy via a crafted web site (CVE-2015-1210). The OriginCanAccessServiceWorkers function in content/browser/service_worker/service_worker_dispatcher_host.cc in Google Chrome before 40.0.2214.111 does not properly restrict the URI scheme during a ServiceWorker registration, which allows remote attackers to gain privileges via a filesystem: URI (CVE-2015-1211). Multiple unspecified vulnerabilities in Google Chrome before 40.0.2214.111 allow attackers to cause a denial of service or possibly have other impact via unknown vectors (CVE-2015-1212).
