Improper Verification of Cryptographic Signature in node-forge

### ImpactRSA PKCS#1 v1.5 signature verification code does not check for tailing garbage bytes after decoding a `DigestInfo` ASN.1 structure. This can allow padding bytes to be removed and garbage data added to forge a signature when a low public exponent is being used.### PatchesThe issue has been addressed in `node-forge` `1.3.0`.### ReferencesFor more information, please see["Bleichenbacher's RSA signature forgery based on implementation error"](https://mailarchive.ietf.org/arch/msg/openpgp/5rnE9ZRN1AokBVj3VqblGlP63QE/)by Hal Finney.### For more informationIf you have any questions or comments about this advisory:* Open an issue in [forge](https://github.com/digitalbazaar/forge)* Email us at [example email address](mailto:security@digitalbazaar.com)
