Multiple unspecified vulnerabilities in Google Chrome before 38.0.2125.101 allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

The NavigationScheduler::schedulePageBlock function in core/loader/NavigationScheduler.cpp in Blink, as used in Google Chrome before 38.0.2125.101, does not properly provide substitute data for pages blocked by the XSS auditor, which allows remote attackers to obtain sensitive information via a crafted web site.

Use-after-free vulnerability in Blink, as used in Google Chrome before 38.0.2125.101, allows remote attackers to cause a denial of service or possibly have unspecified other impact via crafted JavaScript code that triggers a widget-position update that improperly interacts with the render tree, related to the FrameView::updateLayoutAndStyleForPainting function in core/frame/FrameView.cpp and the RenderLayerScrollableArea::setScrollOffset function in core/rendering/RenderLayerScrollableArea.cpp.

Google Chrome before 38.0.2125.101 and Chrome OS before 38.0.2125.101 do not properly handle the interaction of IPC and Google V8, which allows remote attackers to execute arbitrary code via vectors involving JSON data, related to improper parsing of an escaped index by ParseJsonObject in json-parser.h.

Multiple unspecified vulnerabilities in Google V8 before 3.28.71.15, as used in Google Chrome before 38.0.2125.101, allow attackers to cause a denial of service or possibly have other impact via unknown vectors.

Use-after-free vulnerability in the ProcessingInstruction::setXSLStyleSheet function in core/dom/ProcessingInstruction.cpp in the DOM implementation in Blink, as used in Google Chrome before 38.0.2125.101, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

The Instance::HandleInputEvent function in pdf/instance.cc in the PDFium component in Google Chrome before 38.0.2125.101 interprets a certain -1 value as an index instead of a no-visible-page error code, which allows remote attackers to cause a denial of service (out-of-bounds read) via unspecified vectors.

Use-after-free vulnerability in the Event::currentTarget function in core/events/Event.cpp in Blink, as used in Google Chrome before 38.0.2125.101, allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via crafted JavaScript code that accesses the path property of an Event object.

base/memory/shared_memory_win.cc in Google Chrome before 38.0.2125.101 on Windows does not properly implement read-only restrictions on shared memory, which allows attackers to bypass a sandbox protection mechanism via unspecified vectors.

The chrome_pdf::CopyImage function in pdf/draw_utils.cc in the PDFium component in Google Chrome before 38.0.2125.101 does not properly validate image-data dimensions, which allows remote attackers to cause a denial of service (out-of-bounds read) or possibly have unspecified other impact via unknown vectors.
