"The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as
referenced in the RHSA-2017:0002 advisory.

    Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network
    applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and
    efficient, perfect for data-intensive real-time applications that run across distributed devices.

    The following packages have been upgraded to a newer upstream version: rh-nodejs4-nodejs (4.6.2), rh-
    nodejs4-http-parser (2.7.0). (BZ#1388097)

    Security Fix(es):

    * It was found that Node.js' tls.checkServerIdentity() function did not properly validate server
    certificates containing wildcards. A malicious TLS server could use this flaw to get a specially crafted
    certificate accepted by a Node.js TLS client. (CVE-2016-7099)

    * It was found that the V8 Zone class was vulnerable to integer overflow 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)

    * A vulnerability was found in c-ares, a DNS resolver library bundled with Node.js. A hostname with an
    escaped trailing dot would have its size calculated incorrectly, leading to a single byte written beyond
    the end of a buffer on the heap. An attacker able to provide such a hostname to an application using
    c-ares, could potentially cause that application to crash. (CVE-2016-5180)

    * It was found that the reason argument in ServerResponse#writeHead() was not properly validated. A remote
    attacker could possibly use this flaw to conduct an HTTP response splitting attack via a specially-crafted
    HTTP request. (CVE-2016-5325)

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

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