CVE-2018-12115
The MITRE CVE dictionary describes this issue as:
In all versions of Node.js prior to 6.14.4, 8.11.4 and 10.9.0 when used with UCS-2 encoding (recognized by Node.js under the names `'ucs2'`, `'ucs-2'`, `'utf16le'` and `'utf-16le'`), `Buffer#write()` can be abused to write outside of the bounds of a single `Buffer`. Writes that start from the second-to-last position of a buffer cause a miscalculation of the maximum length of the input bytes to be written.

Statement
Openshift Container Platform 3.x versions are potentially vulnerable via the nodejs-slave-jenkins and nodejs-node-jenkins components. However a build would have to occur with a malicious jenkins pipeline, or nodejs source code supplied by an attacker, reducing the impact of this flaw to moderate.
