gnutls: vulnerable to Minerva side-channel information leak

A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLSPRIVKEYFLAGREPRODUCIBLE flag, it can result in a noticeable step in nonce...

Observable Discrepancy

Overview BouncyCastle is a C implementation of cryptographic algorithms. Affected versions of this package are vulnerable to Observable Discrepancy due to the timing difference between exceptions thrown when processing RSA key exchange handshakes, AKA Marvin. Note: The implemented fix mitigates t...

Timing Based Side-Channel Attack

Libgcrypt is vulnerable to a timing-based side-channel attack. The vulnerability is due to the handling of RSA decryption, which may allow a remote attacker to initiate a Bleichenbacher-style attack and decrypt arbitrary RSA ciphertexts...

The vulnerability of the PrivateDecrypt() function in the cryptographic library of the Node.js software platform, which allows a attacker to execute the Bleichenbacher attack or the Marvin attack.

The vulnerability of the PrivateDecrypt function in the Node.js software library is related to the use of hidden auxiliary channels due to a discrepancy in the timing of decrypting valid and invalid encrypted texts based on the PKCS1 v1.5 cryptographic standard. Exploiting this vulnerability allo...
