crash or execute arbitrary code with the privileges of the sandboxed
render process. (CVE-2015-1209)
It was discovered that V8 did not properly consider frame access
restrictions when throwing exceptions in some circumstances. If a user
were tricked in to opening a specially crafted website, an attacker could
potentially exploit this to bypass same origin restrictions.
(CVE-2015-1210)

potentially exploit this to bypass security restrictions. (CVE-2015-1211)
Multiple security issues were discovered in Chromium. If a user were
