OpenSSL v1.0.0.g Release Notes

Release Date: 2012-03-12 // about 12 years ago
    • Fix MMA (Bleichenbacher's attack on PKCS #1 v1.5 RSA padding) weakness in CMS and PKCS7 code. When RSA decryption fails use a random key for content decryption and always return the same error. Note: this attack needs on average 220 messages so it only affects automated senders. The old behaviour can be re-enabled in the CMS code by setting the CMS_DEBUG_DECRYPT flag: this is useful for debugging and testing where an MMA defence is not necessary. Thanks to Ivan Nestlerode [email protected] for discovering this issue. [CVE-2012-0884][]
