"The version of Google Chrome installed on the remote Mac OS X host is
prior to 49.0.2623.75. It is, therefore, affected by multiple
vulnerabilities :

  - Multiple overflow conditions exist in the libpng library
    in the png_set_PLTE() and png_get_PLTE() functions due
    to improper handling of bit depths less than eight. A
    remote attacker can exploit this, via a specially
    crafted PNG image, to cause a denial of service
    condition or the execution of arbitrary code.
    (CVE-2015-8126)

  - An unspecified flaw exists in Blink that allows an
    attacker to bypass the same-origin policy.
    (CVE-2016-1630)

  - An unspecified flaw exists in the Pepper plugin that
    allows an attacker to bypass the same-origin policy.
    (CVE-2016-1631)

  - A bad cast flaw exists in the Extensions component that
    allows an attacker to have an unspecified impact.
    (CVE-2016-1632)

  - Multiple use-after-free errors exist in Blink. A remote
    attacker can exploit these issues to dereference already
    freed memory, resulting in the execution of arbitrary
    code. (CVE-2016-1633, CVE-2016-1634, CVE-2016-1635)

  - An unspecified flaw exists that allows an attacker to
    bypass SRI validation. (CVE-2016-1636)

  - An unspecified flaw exists that allows an attacker to
    disclose sensitive information. (CVE-2016-1637)

  - An unspecified flaw exists that allows an attacker to
    bypass the webAPI. (CVE-2016-1638)

  - A use-after-free error exists in WebRTC. A remote
    attacker can exploit this issue to dereference already
    freed memory, resulting in the execution of arbitrary
    code. (CVE-2016-1639)

  - An unspecified origin confusion flaw exists in the
    Extensions UI that allows an attacker to have an
    unspecified impact. (CVE-2016-1640)

  - A use-after-free error exists in Favicon. A remote
    attacker can exploit this issue to dereference already
    freed memory, resulting in the execution of arbitrary
    code. (CVE-2016-1641)

  - Multiple flaws exist that allow a remote attacker to
    execute arbitrary code. (CVE-2016-1642)

  - Multiple unspecified flaws exist in Google V8 in
    runetime-scopes.cc that allows an attacker to cause a
    denial of service condition or the execution of
    arbitrary code. (CVE-2016-2843)");
