What is CVE-2018-12115?

The vulnerability in Node.js prior to versions 6.14.4, 8.11.4, and 10.9.0 arises from a flaw when utilizing UCS-2 encoding, which is also known as 'ucs2', 'utf16le', or 'utf-16le'. The Buffer#write() function can be exploited to write data beyond the allocated boundaries of a buffer. As a result, attempts to write starting from the second-to-last position could miscalculate the maximum length of the input bytes, leading to potential data corruption or application crashes.
