determining whether a URL is associated with a WebUI SiteInstance. If a
user were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to bypass security restrictions.
(CVE-2015-1266)
It was discovered that Blink did not properly restrict the creation
context during creation of a DOM wrapper. If a user were tricked in to
opening a specially crafted website, an attacker could potentially exploit
this to bypass same-origin restrictions. (CVE-2015-1267, CVE-2015-1268)
It was discovered that Chromium did not properly canonicalize DNS hostnames
before comparing to HSTS or HPKP preload entries. An attacker could
potentially exploit this to bypass intended access restrictions.
