NVD Description

Note: Versions mentioned in the description apply only to the upstream nodejs package and not the nodejs package as distributed by Alpine. See How to fix? for Alpine:3.15 relevant fixed versions and status.

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 &#39;ucs2&#39;, &#39;ucs-2&#39;, &#39;utf16le&#39; and &#39;utf-16le&#39;), 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.
