Technical details
Vulnerability (2) related to browser/browsing_data/browsing_data_remover.cc which mistakenly deletes HPKP pins during cache clearing.
Vulnerability (3) related to browser/safe_browsing/srt_field_trial_win.cc. Google Chrome does not use the HTTPS service to obtain the Software Removal Tool. This vulnerability can be exploited to spoof the chrome_cleanup_tool.exe (aka CCT) file.
Vulnerability (4) permits cross-origin loading of CSS stylesheets by a ServiceWorker even when the stylesheet download has an incorrect MIME type. It allows to bypass the Same Origin Policy. This vulnerability related to WebKit/Source/core/css/StyleSheetContents.cpp file.
Vulnerability (5) related to SkOpCoincidence.cpp and SkPathOpsCommon.cpp files. It can be exploited to cause heap-based buffer overflow.
Vulnerability (6) caused by improper interaction between field updates and JavaScript code that triggers a frame deletion. It allows to cause use-after-free. Vulnerability (6) different than CVE-2016-1701.
Vulnerability (7) related to content/renderer/media/canvas_capture_handler.cc. It allows to cause heap-based buffer overflow.
Vulnerability (8) related to Google V8 before 5.0.71.40. This vulnerability caused by improper processing of external string sizes. It allows to cause out-of-bounds read.
Vulnerability (10) related to CPDF_DIBSource::CreateDecoder function in core/fpdfapi/fpdf_render/fpdf_render_loadimage.cpp in PDFium. It allows to cause out-of-bounds read.
Vulnerability (11) related to core/fxge/ge/fx_ge_text.cpp in PDFium and allows out-of-bounds read.
Vulnerabilities (12) and (13) related to numbers.c in libxslt before 1.1.29 and allow to cause integer overflow, resource consumption and out-of-bounds heap memory access.
Vulnerability (14) related to ServiceWorkerContainer::registerServiceWorkerImpl function in WebKit/Source/modules/serviceworkers/ServiceWorkerContainer.cpp in Blink. It allows to bypass the Content Security Policy (CSP) protection mechanism.
Vulnerability (15) related to opj_j2k_read_SPCod_SPCoc function in j2k.c in OpenJPEG, as used in PDFium, and allows to cause heap-based buffer overflow.
Vulnerability (16) related to ports/SkFontHost_FreeType.cpp in Skia. This vulnerability allows to cause use-after-free.
Vulnerability (17) related to ToV8Value function in content/child/v8_value_converter_impl.cc in the V8 bindings.
Vulnerability (18) related to objects.cc in V8 and allows to cause heap-based buffer overflow.
Vulnerability (19) related to uri.js in V8. It can be exploited by calling the decodeURI function and leveraging “type confusion”.
Vulnerability (20) related to extensions/renderer/resources/binding.js file and allows to bypass the Same Origin Policy.
Vulnerability (21) related to FrameLoader.cpp and LocalFrame.cpp files. It can be exploited by leveraging the mishandling of Document reattachment during destruction.
