Red Hat Security Advisory 2017-3002-01
Posted Oct 23, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-3002-01 - 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 later upstream version: rh-nodejs4-nodejs. Security Fix: It was found that Node.js was using a non-randomized seed when populating hash tables. An attacker, able to supply a large number of inputs, could send specially crafted entries to the Node.js application, maximizing hash collisions to trigger an excessive amount of CPU usage, resulting in a denial of service.

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 later upstream version:
rh-nodejs4-nodejs (4.8.4). (BZ#1476314)

Security Fix(es):

* It was found that Node.js was using a non-randomized seed when populating
hash tables. An attacker, able to supply a large number of inputs, could
send specially crafted entries to the Node.js application, maximizing hash
collisions to trigger an excessive amount of CPU usage, resulting in a
denial of service. (CVE-2017-11499)

Bug Fix(es):

* The /opt/rh/rh-nodejs4/root/usr/share/licenses/ directory was not owned
by any package. Consequently, when the rh-nodejs4 collection was
uninstalled, the directory was not removed. This bug has been fixed, and
the aforementioned directory is correctly removed after uninstalling
rh-nodejs4. (BZ#1316626)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1316626 - Leftover /opt/rh/rh-nodejs4/root/usr/share/licenses after uninstallation
1475327 - CVE-2017-11499 nodejs: Constant Hashtable Seeds vulnerability
