(RHSA-2017:3002) Moderate: rh-nodejs4-nodejs security and bug fix update

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)
