a user were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to bypass same-origin restrictions.
(CVE-2015-1236)

A use-after-free was discovered in Chromium. If a user were tricked in to

this to cause a denial of service via renderer crash, or execute arbitrary
code with the privileges of the sandboxed render process. (CVE-2015-1237)
