What is CVE-2018-7166?

A vulnerability exists in all versions of Node.js 10 prior to 10.9.0 that allows the Buffer.alloc() function to return uninitialized memory due to a flaw in argument processing. The encoding argument can mistakenly be interpreted as a start index for the filling operation, which may lead to returning uninitialized, sensitive data if arguments are derived from user inputs. This poses a significant risk as it may expose sensitive information stored in memory.

Affected Version(s)

Node.js All versions of Node.js 10 prior to 10.9.0
