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.

Integer overflow in the CJBig2_Image::expand function in fxcodec/jbig2/JBig2_Image.cpp in PDFium, as used in Google Chrome before 44.0.2403.89, allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via large height and stride values.

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)."

Use-after-free vulnerability in the GPU process implementation in Google Chrome before 44.0.2403.89 allows remote attackers to cause a denial of service or possibly have unspecified other impact by leveraging the continued availability of a GPUChannelHost data structure during Blink shutdown, related to content/browser/gpu/browser_gpu_channel_host_factory.cc and content/renderer/render_thread_impl.cc.

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.

Use-after-free vulnerability in the accessibility implementation in Google Chrome before 44.0.2403.89 allows remote attackers to cause a denial of service or possibly have unspecified other impact by leveraging lack of certain validity checks for accessibility-tree data structures.

The ucnv_io_getConverterName function in common/ucnv_io.cpp in International Components for Unicode (ICU), as used in Google Chrome before 44.0.2403.89, mishandles converter names with initial x- substrings, which allows remote attackers to cause a denial of service (read of uninitialized memory) or possibly have unspecified other impact via a crafted file.

PDFium, as used in Google Chrome before 44.0.2403.89, does not properly handle certain out-of-memory conditions, which allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted PDF document that triggers a large memory allocation.

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.
