"The remote Redhat Enterprise Linux 7 host has a package installed that is affected by a vulnerability as referenced in
the RHSA-2017:0880 advisory.

    V8 is Google's open source JavaScript engine. V8 is written in C++ and is used in Google Chrome, the open
    source browser from Google. V8 implements ECMAScript as specified in ECMA-262, 3rd edition.

    Security Fix(es):

    * An integer-overflow flaw was found in V8's Zone class when allocating new memory (Zone::New() and
    Zone::NewExpand()). An attacker with the ability to manipulate a large zone could crash the application
    or, potentially, execute arbitrary code with the application privileges. (CVE-2016-1669)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
