On Padding Oracle Attacks

Poodle is a vulnerability found in late 2014, and it is still occasionally seen during penetration tests. The vulnerability allows an attacker with a man-in-the-middle position to downgrade a secure connection between a client and a server to the vulnerable SSLv3. After the connection is...

Issue Overview: Weak ElGamal key parameters in PublicKey/ElGamal.py allow attackers to obtain sensitive information by reading ciphertext: lib/Crypto/PublicKey/ElGamal.py in PyCrypto through 2.6.1 generates weak ElGamal key parameters, which allows attackers to obtain sensitive information by...

erlang: TLS server vulnerable to Adaptive Chosen Ciphertext attack allowing plaintext recovery or MITM attack

An erlang TLS server configured with cipher suites using RSA key exchange, may be vulnerable to an Adaptive Chosen Ciphertext attack AKA Bleichenbacher attack against RSA. This may result in plain-text recovery of encrypted messages and/or a man-in-the-middle MiTM attack, despite the attacker not...
