Technical details
Vulnerability (2) related to sycc422_to_rgb and sycc444_to_rgb functions in fxcodec/codec/fx_codec_jpx_opj.cpp.
Vulnerability (3) related to Blink version which does not ensure that cryptographicallyRandomValues is used. Exploitation of this vulnerability can lead to defeat cryptographic protection.
Vulnerability (4) related to CSPSource::schemeMatches function in WebKit/Source/core/frame/csp/CSPSource.cpp in the Content Security Policy (CSP) implementation which does not apply http policies to HTTPS URLs and does not apply ws polivies to WSS URLs. Exploitation of this vulnerability can lead to disclosure of information about specific HSTS sites visits. This vulnerability can be exploited via reading CSP report.
Vulnerability (5) related to CustomButton::AcceleratorPressed function in ui/views/controls/button/custom_button.cc and can be triggered via unknown vectors related to unfocused custom button.
By exploiting vulnerability (6) malicious can spoof document’s origin.
Vulnerability (7) related to UnacceleratedImageBufferSurface class in WebKit/Source/platform/graphics/UnacceleratedImageBufferSurface.cpp. By exploiting this vulnerability malicious can obtain sensitive information from process memory.
Vulnerability (8) related to improper tracking of the destruction of IPWL_FocusHandler and IPWL_Provider objects.
Vulnerability (9) related toLoadIC::UpdateCaches function in ic/ic.cc which does not ensure receiver compatibility.
