3. Description:

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)
