Details

As written in the advisory (Markdown source, shown as plain text).

### Impact RSA PKCS#1 v1.5 signature verification code is lenient in checking the digest algorithm structure. This can allow a crafted structure that steals padding bytes and uses unchecked portion of the PKCS#1 encoded message to forge a signature when a low public exponent is being used. ### Patches The issue has been addressed in `node-forge` `1.3.0`. ### References For 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 information If 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:[email protected])
