tricked in to opening a specially crafted website in a browsing-like
context, an attacker could potentially exploit these to read uninitialized
memory, bypass phishing and malware protection, conduct cross-site
scripting (XSS) attacks, cause a denial of service via application crash,
or execute arbitrary code. (CVE-2017-7793, CVE-2017-7810, CVE-2017-7814,
