CVE-2005-0366: Inadequate Encryption Strength

The integrity check feature in OpenPGP, when handling a message that was encrypted using cipher feedback CFB mode, allows remote attackers to recover part of the plaintext via a chosen-ciphertext attack when the first 2 bytes of a message block are known, and an oracle or other mechanism is...

OpenPGP vulnerable to chosen-ciphertext attacks in cipher feedback (CFB) mode

Overview A vulnerability in OpenPGP may allow attackers to recover partial plaintexts from OpenPGP messages that use symmetric encryption. Description A vulnerability in OpenPGP can be used by attackers to recover partial plaintexts from messages employing symmetric encryption. Researchers Serge...

SSL/TLS implementations disclose side channel information via PKCS #1 v1.5 version number extension

Overview SSL/TLS implementations that respond distinctively to an incorrect PKCS 1 v1.5 encoded SSL/TLS version number expose the premaster secret to a modified Bleichenbacher attack. An attacker could decrypt a given SSL/TLS session or forge a signature on behalf of a vulnerable application's...

CVE-2003-0131

The SSL and TLS components for OpenSSL 0.9.6i and earlier, 0.9.7, and 0.9.7a allow remote attackers to perform an unauthorized RSA private key operation via a modified Bleichenbacher attack that uses a large number of SSL or TLS connections using PKCS 1 v1.5 padding that cause OpenSSL to leak...

Klima-Pokorny-Rosa attack on PKCS #1 v1.5 padding

On some conditions it's possible server's private key to be applied to attacker choosen ciphertext...
