A flaw was found in Bouncy Castle for Java. A remote attacker can exploit an OpenPGP (Open Pretty Good Privacy) Cipher Feedback (CFB) quick-check oracle vulnerability. This oracle, active on symmetric and session-key paths, could allow an attacker to gain sensitive information by observing the results of cryptographic operations. This could lead to the disclosure of confidential data.
