Name of the Vulnerable Software and Affected Versions node-forge versions prior to 1.4.1
Description An issue exists during RSA PKCS#1 v1.5 signature verification where the software fails to validate the element count in nested DigestAlgorithm sequences. This allows attackers to embed garbage bytes within the DigestAlgorithm sequence to forge valid signatures for arbitrary messages when low-exponent RSA keys are used.
Recommendations Update node-forge to version 1.4.1 or later.
