Details

An out of bounds write was discovered in Blink. 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. (CVE-2016-1660)

It was discovered that Blink assumes that a frame which passes same-origin
checks is local in some cases. 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.
(CVE-2016-1661)

A use-after-free was discovered in the V8 bindings in Blink. 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. (CVE-2016-1663)

It was discovered that the JSGenericLowering class in V8 mishandles
comparison operators. If a user were tricked in to opening a specially
crafted website, an attacker could potentially exploit this to obtain
sensitive information. (CVE-2016-1665)

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.
(CVE-2016-1666)

It was discovered that the TreeScope::adoptIfNeeded function in Blink
does not prevent script execution during node-adoption operations. If a
user were tricked in to opening a specially crafted website, an attacker
could potentially exploit this to bypass same origin restrictions.
(CVE-2016-1667)

It was discovered that the forEachForBinding in the V8 bindings in Blink
uses an improper creation context. If a user were tricked in to opening a
specially crafted website, an attacker could potentially exploit this to
bypass same origin restrictions. (CVE-2016-1668)

A buffer overflow was discovered in V8. 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. (CVE-2016-1669)

A race condition was discovered in ResourceDispatcherHostImpl in Chromium.
An attacker could potentially exploit this to make arbitrary HTTP
requests. (CVE-2016-1670)
