CVE-2012-0884 Information

Description

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.
