Summary

The host is installed with Node.js and is prone to an out-of-bounds write vulnerability.

Insight

Insight

An OOB write in Buffer can be used to write to memory outside of a Buffer's memory space. This can corrupt unrelated Buffer objects or cause the Node.js process to crash. 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 Software
