Description

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.

Affected configurations

• nodejs node.js (< 6.14.4) • nodejs node.js (>= 8.0.0 < 8.11.4) • nodejs node.js (>= 10.0.0 < 10.9.0) • redhat openshift container platform 3.11
