opening a specially crafted website, an attacker could potentially
exploit this to execute arbitrary code. (CVE-2016-5273)

A use-after-free was discovered in web animations during restyling. If a
user were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to cause a denial of service via
application crash, or execute arbitrary code. (CVE-2016-5274)

A buffer overflow was discovered when working with empty filters during
