"It was discovered that ContainerNode::parserInsertBefore in Blink
would incorrectly proceed with a DOM tree insertion 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-2015-6755)

A use-after-free was discovered in the service worker implementation
in Chromium. 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 with the
privileges of the user invoking the program. (CVE-2015-6757)

It was discovered that Blink did not ensure that the origin of
LocalStorage resources are considered unique. If a user were tricked
in to opening a specially crafted website, an attacker could
potentially exploit this to obtain sensitive information.
(CVE-2015-6759)

A race condition and memory corruption was discovered in FFmpeg. 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 renderer crash, or execute arbitrary code with the privileges of
the sandboxed render process. (CVE-2015-6761)

It was discovered that CSSFontFaceSrcValue::fetch in Blink did not use
CORS 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-2015-6762)

Multiple security issues were discovered in Chromium. If a user were
tricked in to opening a specially crafted website, an attacker could
potentially exploit these to read uninitialized memory, cause a denial
of service via application crash or execute arbitrary code with the
privileges of the user invoking the program. (CVE-2015-6763)

Multiple security issues were discovered in V8. If a user were tricked
in to opening a specially crafted website, an attacker could
potentially exploit these to read uninitialized memory, cause a denial
of service via renderer crash or execute arbitrary code with the
privileges of the sandboxed render process. (CVE-2015-7834).
