Multiple unspecified vulnerabilities in Google Chrome before 45.0.2454.85 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

The FrameFetchContext::updateTimingInfoForIFrameNavigation function in core/loader/FrameFetchContext.cpp in Blink, as used in Google Chrome before 45.0.2454.85, does not properly restrict the availability of IFRAME Resource Timing API times, which allows remote attackers to obtain sensitive information via crafted JavaScript code that leverages a history.back call.

Use-after-free vulnerability in the shared-timer implementation in Blink, as used in Google Chrome before 45.0.2454.85, allows remote attackers to cause a denial of service or possibly have unspecified other impact by leveraging erroneous timer firing, related to ThreadTimers.cpp and Timer.cpp.

The RuntimeEventRouter::OnExtensionUninstalled function in extensions/browser/api/runtime/runtime_api.cc in Google Chrome before 45.0.2454.85 does not ensure that the setUninstallURL preference corresponds to the URL of a web site, which allows user-assisted remote attackers to trigger access to an arbitrary URL via a crafted extension that is uninstalled.

The WebRequest API implementation in extensions/browser/api/web_request/web_request_api.cc in Google Chrome before 45.0.2454.85 does not properly consider a request's source before accepting the request, which allows remote attackers to bypass intended access restrictions via a crafted (1) app or (2) extension.

The UnescapeURLWithAdjustmentsImpl implementation in net/base/escape.cc in Google Chrome before 45.0.2454.85 does not prevent display of Unicode LOCK characters in the omnibox, which makes it easier for remote attackers to spoof the SSL lock icon by placing one of these characters at the end of a URL, as demonstrated by the omnibox in localizations for right-to-left languages.

Multiple use-after-free vulnerabilities in the PrintWebViewHelper class in components/printing/renderer/print_web_view_helper.cc in Google Chrome before 45.0.2454.85 allow user-assisted remote attackers to cause a denial of service or possibly have unspecified other impact by triggering nested IPC messages during preparation for printing, as demonstrated by messages associated with PDF documents in conjunction with messages about printer capabilities.

Use-after-free vulnerability in the SkMatrix::invertNonIdentity function in core/SkMatrix.cpp in Skia, as used in Google Chrome before 45.0.2454.85, allows remote attackers to cause a denial of service or possibly have unspecified other impact by triggering the use of matrix elements that lead to an infinite result during an inversion calculation.

The DOM implementation in Blink, as used in Google Chrome before 45.0.2454.85, allows remote attackers to bypass the Same Origin Policy via unspecified vectors.

The NavigatorServiceWorker::serviceWorker function in modules/serviceworkers/NavigatorServiceWorker.cpp in Blink, as used in Google Chrome before 45.0.2454.85, allows remote attackers to bypass the Same Origin Policy by accessing a Service Worker.

The ContainerNode::parserRemoveChild function in core/dom/ContainerNode.cpp in Blink, as used in Google Chrome before 45.0.2454.85, does not check whether a node is expected, which allows remote attackers to bypass the Same Origin Policy or cause a denial of service (DOM tree corruption) via a web site with crafted JavaScript code and IFRAME elements.

Multiple unspecified vulnerabilities in Google Chrome before 44.0.2403.89 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

The Spellcheck API implementation in Google Chrome before 44.0.2403.89 does not use an HTTPS session for downloading a Hunspell dictionary, which allows man-in-the-middle attackers to deliver incorrect spelling suggestions or possibly have unspecified other impact via a crafted file, a related issue to CVE-2015-1263.

Blink, as used in Google Chrome before 44.0.2403.89, enables a quirks-mode exception that limits the cases in which a Cascading Style Sheets (CSS) document is required to have the text/css content type, which allows remote attackers to bypass the Same Origin Policy via a crafted web site, related to core/fetch/CSSStyleSheetResource.cpp.

Cross-site scripting (XSS) vulnerability in the V8ContextNativeHandler::GetModuleSystem function in extensions/renderer/v8_context_native_handler.cc in Google Chrome before 44.0.2403.89 allows remote attackers to inject arbitrary web script or HTML by leveraging the lack of a certain V8 context restriction, aka a Blink "Universal XSS (UXSS)."

The XSSAuditor::canonicalize function in core/html/parser/XSSAuditor.cpp in the XSS auditor in Blink, as used in Google Chrome before 44.0.2403.89, does not properly choose a truncation point, which makes it easier for remote attackers to obtain sensitive information via an unspecified linear-time attack.

The LocalFrame::isURLAllowed function in core/frame/LocalFrame.cpp in Blink, as used in Google Chrome before 44.0.2403.89, does not properly check for a page's maximum number of frames, which allows remote attackers to cause a denial of service (invalid count value and use-after-free) or possibly have unspecified other impact via crafted JavaScript code that makes many createElement calls for IFRAME elements.

Multiple integer overflows in the XML_GetBuffer function in Expat through 2.1.0, as used in Google Chrome before 44.0.2403.89 and other products, allow remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via crafted XML data, a related issue to CVE-2015-2716.

Multiple use-after-free vulnerabilities in fpdfsdk/src/javascript/Document.cpp in PDFium, as used in Google Chrome before 44.0.2403.89, allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted PDF document, related to the (1) Document::delay and (2) Document::DoFieldDelay functions.

core/loader/ImageLoader.cpp in Blink, as used in Google Chrome before 44.0.2403.89, does not properly determine the V8 context of a microtask, which allows remote attackers to bypass Content Security Policy (CSP) restrictions by providing an image from an unintended source.
