Pending analysis

Type:

CWE-787 Out-of-bounds Write

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 `&#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.
