Name of the Vulnerable Software and Affected Versions Node.js versions prior to 6.14.4 Node.js versions prior to 8.11.4 Node.js versions prior to 10.9.0

Description The issue arises when Node.js is used with UCS-2 encoding, which is recognized under the names ucs2, ucs-2, utf16le, and utf-16le. In this context, the Buffer#write() function can be exploited to write beyond the boundaries of a single buffer. Specifically, writes that initiate from the second-to-last position of a buffer lead to a miscalculation of the maximum length of the input bytes to be written.

Recommendations For versions prior to 6.14.4, update to version 6.14.4 or later. For versions prior to 8.11.4, update to version 8.11.4 or later. For versions prior to 10.9.0, update to version 10.9.0 or later.
