CVE-2018-21270
Versions less than 0.0.6 of the Node.js stringstream module are vulnerable to an out-of-bounds read because of allocation of uninitialized buffers when a number is passed in the input stream (when using Node.js 4.x).
Does this matter?
Lower severity and a low EPSS score (3.68%). Track it; it rarely justifies an emergency change on its own.
