Improper Verification of Cryptographic Signature in node-forge
RSA PKCS#1 v1.5 signature verification code is not properly checking DigestInfo
for a proper ASN.1 structure. This can lead to successful verification with signatures that contain invalid structures but a valid digest.
The issue has been addressed in node-forge
1.3.0
.
If you have any questions or comments about this advisory:
Improper Verification of Cryptographic Signature in node-forge
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.
The issue has been addressed in node-forge
1.3.0

Improper Verification of Cryptographic Signature in node-forge
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.
