9. Heap corruption vulnerability in PDFium can potentially be exploited remotely via crafted PDF files to perform an out of bounds memory read and possibly cause denial of service;
10. A heap use after free vulnerability in PDFium can potentially be exploited remotely via crafted PDF files to cause heap corruption, and, possibly, denial of service as a consequence;
11. Insufficient validation in bitmap handiling in Blink can be exploited remotely via crafted HTML pages to cause heap corruption, and, possibly, denial of service as a consequence;
