Overview

safe-compare is a constant-time comparison algorithm to prevent timing attacks..

Affected versions of the package are vulnerable to Insecure Credential Comparison. It used the bufferAlloc constructor incorrectly, which caused the password string to be "padded" with itself. This means that the passwords "a" and "aaaaaaaaaaaaa" would be equal.

Remediation

Upgrade safe-compare to version 1.1.2 or higher.
