Description
Impact
RSA 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.
Patches
The issue has been addressed in node-forge 1.3.0.

NVD description
Forge (also called `node-forge`) is a native implementation of Transport Layer Security in JavaScript. Prior to version 1.3.0, RSA 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. The issue has been addressed in `node-forge` version 1.3.0. There are currently no known workarounds.
