. Apple WebKit: Bypass pop-up blocker via cross-origin or sandboxed iframe.
CVE-2017-2371
The second argument of window.open is a name for the new window. If there's a frame that has same name, it will try to load the URL in that. If not, it just tries to create a new window and pop-up. But without the user's click event, its attempt will fail.
Here's some snippets.
RefPtr
RefPtr DOMWindow::createWindow(const String& urlString, const AtomicString& frameName, const WindowFeatures& windowFeatures, DOMWindow& activeWindow, Frame& firstFrame, Frame& openerFrame, std::function
...
}
RefPtr createWindow(Frame& openerFrame, Frame& lookupFrame, const FrameLoadRequest& request, const WindowFeatures& features, bool& created) { ASSERT(!features.dialog || request.frameName().isEmpty());
created = false;
---------------- (2) -----------------------
if (!request.frameName().isEmpty() && request.frameName() != "_blank") {
if (RefPtr<Frame> frame = lookupFrame.loader().findFrameForNavigation(request.frameName(), openerFrame.document())) {
if (request.frameName() != "_self") {
if (Page* page = frame->page())
page->chrome().focus();
}
return frame;
}
}
--------------------------------------------
<<<<<----------- failed to find the frame, creates a new one.
}
The logic of the code (1) depends on the assumption that if |m_frame->tree().find(frameName)| succeeds, |lookupFrame.loader().findFrameForNavigation| at (2) will also succeed. If we could make |m_frame->tree().find(frameName)| succeed but |lookupFrame.loader().findFrameForNavigation| fail, a new window will be created and popped up without the user's click event.
Let's look into |findFrameForNavigation|.
Frame FrameLoader::findFrameForNavigation(const AtomicString& name, Document activeDocument) { Frame* frame = m_frame.tree().find(name);
// FIXME: Eventually all callers should supply the actual activeDocument so we can call canNavigate with the right document.
if (!activeDocument)
activeDocument = m_frame.document();
if (!activeDocument->canNavigate(frame))
return nullptr;
return frame;
}
bool Document::canNavigate(Frame* targetFrame) { ... if (isSandboxed(SandboxNavigation)) { <<<--------------- (1) if (targetFrame->tree().isDescendantOf(m_frame)) return true;
const char* reason = "The frame attempting navigation is sandboxed, and is therefore disallowed from navigating its ancestors.";
if (isSandboxed(SandboxTopNavigation) && targetFrame == &m_frame->tree().top())
reason = "The frame attempting navigation of the top-level window is sandboxed, but the 'allow-top-navigation' flag is not set.";
printNavigationErrorMessage(targetFrame, url(), reason);
return false;
}
...
if (canAccessAncestor(securityOrigin(), targetFrame)) <<<------------------- (2)
return true;
...
return false;
}
There are two points to make |Document::canNavigate| return false.
(1). Using a sandboxed iframe.
(2). Using a cross-origin iframe.
Tested on Safari 10.0.2 (12602.3.12.0.1).

iTunes and Software Update on the device will automatically check Apple's update server on its weekly schedule. When an update is detected, it is downloaded and the option to be installed is presented to the user when the iOS device is docked. We recommend applying the update immediately if possible. Selecting Don't Install will present the option the next time you connect your iOS device.
The automatic update process may take up to a week depending on the day that iTunes or the device checks for updates. You may manually obtain the update via the Check for Updates button within iTunes, or the Software Update on your device.
To check that the iPhone, iPod touch, or iPad has been updated:
- Navigate to Settings
- Select General
- Select About.
Information will also be posted to the Apple Security Updates web site: https://support.apple.com/kb/HT201222

webkit2gtk vulnerabilities
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 16.10
- Ubuntu 16.04 LTS
Summary:
Several security issues were fixed in WebKitGTK+.
Software Description: - webkit2gtk: Web content engine library for GTK+
Details:
A large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 16.10: libjavascriptcoregtk-4.0-18 2.14.5-0ubuntu0.16.10.1 libwebkit2gtk-4.0-37 2.14.5-0ubuntu0.16.10.1
Ubuntu 16.04 LTS: libjavascriptcoregtk-4.0-18 2.14.5-0ubuntu0.16.04.1 libwebkit2gtk-4.0-37 2.14.5-0ubuntu0.16.04.1
This update uses a new upstream release, which includes additional bug fixes. After a standard system update you need to restart any applications that use WebKitGTK+, such as Epiphany, to make all the necessary changes.

But without the user\u0027s click event, its attempt will fail. \n\nHere\u0027s some snippets. \n\nRefPtr\u003cDOMWindow\u003e DOMWindow::open(const String\u0026 urlString, const AtomicString\u0026 frameName, const String\u0026 windowFeaturesString,\n DOMWindow\u0026 activeWindow, DOMWindow\u0026 firstWindow)\n{\n ... \n ---------------- (1) -----------------------\n if (!firstWindow.allowPopUp()) { \u003c\u003c---- checks there\u0027s the user\u0027s click event. \n // Because FrameTree::find() returns true for empty strings, we must check for empty frame names. \n // Otherwise, illegitimate window.open() calls with no name will pass right through the popup blocker. \n if (frameName.isEmpty() || !m_frame-\u003etree().find(frameName))\n return nullptr;\n }\n --------------------------------------------\n ... \n RefPtr\u003cFrame\u003e result = createWindow(urlString, frameName, parseWindowFeatures(windowFeaturesString), activeWindow, *firstFrame, *m_frame);\n return result ? result-\u003edocument()-\u003edomWindow() : nullptr;\n}\n\n\nRefPtr\u003cFrame\u003e DOMWindow::createWindow(const String\u0026 urlString, const AtomicString\u0026 frameName, const WindowFeatures\u0026 windowFeatures, DOMWindow\u0026 activeWindow, Frame\u0026 firstFrame, Frame\u0026 openerFrame, std::function\u003cvoid (DOMWindow\u0026)\u003e prepareDialogFunction)\n{\n ... \n RefPtr\u003cFrame\u003e newFrame = WebCore::createWindow(*activeFrame, openerFrame, frameRequest, windowFeatures, created);\n if (!newFrame)\n return nullptr;\n\n ... \n}\n\nRefPtr\u003cFrame\u003e createWindow(Frame\u0026 openerFrame, Frame\u0026 lookupFrame, const FrameLoadRequest\u0026 request, const WindowFeatures\u0026 features, bool\u0026 created)\n{\n ASSERT(!features.dialog || request.frameName().isEmpty());\n\n created = false;\n\n ---------------- (2) -----------------------\n if (!request.frameName().isEmpty() \u0026\u0026 request.frameName() != \"_blank\") {\n if (RefPtr\u003cFrame\u003e frame = lookupFrame.loader().findFrameForNavigation(request.frameName(), openerFrame.document())) {\n if (request.frameName() != \"_self\") {\n if (Page* page = frame-\u003epage())\n page-\u003echrome().focus();\n }\n return frame;\n }\n }\n --------------------------------------------\n\n \u003c\u003c\u003c\u003c\u003c----------- failed to find the frame, creates a new one. \n}\n\nThe logic of the code (1) depends on the assumption that if |m_frame-\u003etree().find(frameName)| succeeds, |lookupFrame.loader().findFrameForNavigation| at (2) will also succeed. If we could make |m_frame-\u003etree().find(frameName)| succeed but |lookupFrame.loader().findFrameForNavigation| fail, a new window will be created and popped up without the user\u0027s click event. \n\n\n\nLet\u0027s look into |findFrameForNavigation|. \n\nFrame* FrameLoader::findFrameForNavigation(const AtomicString\u0026 name, Document* activeDocument)\n{\n Frame* frame = m_frame.tree().find(name);\n\n // FIXME: Eventually all callers should supply the actual activeDocument so we can call canNavigate with the right document. \n if (!activeDocument)\n activeDocument = m_frame.document();\n\n if (!activeDocument-\u003ecanNavigate(frame))\n return nullptr;\n\n return frame;\n}\n\nbool Document::canNavigate(Frame* targetFrame)\n{\n ... \n if (isSandboxed(SandboxNavigation)) { \u003c\u003c\u003c--------------- (1)\n if (targetFrame-\u003etree().isDescendantOf(m_frame))\n return true;\n\n const char* reason = \"The frame attempting navigation is sandboxed, and is therefore disallowed from navigating its ancestors.\";\n if (isSandboxed(SandboxTopNavigation) \u0026\u0026 targetFrame == \u0026m_frame-\u003etree().top())\n reason = \"The frame attempting navigation of the top-level window is sandboxed, but the \u0027allow-top-navigation\u0027 flag is not set.\";\n\n printNavigationErrorMessage(targetFrame, url(), reason);\n return false;\n }\n\n ... \n\n if (canAccessAncestor(securityOrigin(), targetFrame)) \u003c\u003c\u003c------------------- (2)\n return true;\n\n ... \n\n return false;\n}\n\nThere are two points to make |Document::canNavigate| return false. \n\n(1).
