Google Chrome < 50.0.2661.94 Multiple Vulnerabilities (Mac OS X)

Synopsis :

A web browser installed on the remote Mac OS X host is affected by
multiple vulnerabilities.

Description :

The version of Google Chrome installed on the remote Mac OS X host is
prior to 50.0.2661.94. It is, therefore, affected by multiple
vulnerabilities :

- An out-of-bounds write error exists in Blink that allows
a context-dependent attacker to execute arbitrary code.
(CVE-2016-1660)

- A flaw exists due to improper validation of
user-supplied input when handling cross-process frames.
A context-dependent attacker can exploit this to corrupt
memory, resulting in the execution of arbitrary code.
(CVE-2016-1661)

- A use-after-free error exists in the extensions
component. A context-dependent attacker can exploit this
to dereference already freed memory, resulting in the
execution of arbitrary code. (CVE-2016-1662)

- A use-after-free free error exists in Blink's V8
bindings. A context-dependent attacker can exploit this
to dereference already freed memory, resulting in the
execution of arbitrary code. (CVE-2016-1663)

- An unspecified flaw exists that allows a
context-dependent attacker to spoof the address bar.
(CVE-2016-1664)

- An unspecified flaw exists in V8 that allows a
context-dependent attacker to disclose sensitive
information. (CVE-2016-1665)

- Multiple unspecified vulnerabilities exist that allow a
a context-dependent attacker to execute arbitrary code.
(CVE-2016-1666)

- A same-origin bypass vulnerability exists in Skia in the
pinToByte() function in effects/SkArithmeticMode.cpp due
to improper handling of intermediate color values. An
unauthenticated, remote attacker can exploit this, via
timing attacks using the SVG 'feComposite' filter, to
bypass the same-origin policy. (CVE-2016-5168)
