802725: CVE-2012-0884 openssl: CMS and PKCS#7 Bleichenbacher attack

The MITRE CVE dictionary describes this issue as:

The implementation of Cryptographic Message Syntax (CMS) and PKCS #7 in OpenSSL before 0.9.8u and 1.x before 1.0.0h does not properly restrict certain oracle behavior, which makes it easier for context-dependent attackers to decrypt data via a Million Message Attack (MMA) adaptive chosen ciphertext attack.
