Technical details
Vulnerability (1) related to ModuleSystem::RequireForJsInner function in extensions/renderer/module_system.cc in the Extensions subsystem.
Vulnerability (2) caused by improper implementation of LoadBuffer function. Mishandles data types allows remote attackers to trigger an out-of-bounds write operation, related to compiler/pipeline.cc and compiler/simplified-lowering.cc.
Vulnerability (3) caused by improper implementation of sycc420_to_rgb and sycc422_to_rgb functions in fxcodec/codec/fx_codec_jpx_opj.cpp. It allows to read out-of-bounds via crafted JPEG 2000 data in a PDF document.
Vulnerability (4) allows attackers to cause invalid read operation.
Vulnerability (5) caused by the fact that Google Chrome improperly consider that frame removal may occur during callback execution. It allows remote attackers use-after-free or possibly have unspecified other impact.
Vulnerability (7) caused by incorrectly relies on GetOrigin method. It allows remote attackers to bypass the Same Origin Policy.
Vulnerability (8) caused by improper focus handling for certain about:blank pages in WebContentsImpl::FocusLocationBarByDefault function in content/browser/web_contents/web_contents_impl.cc.
