Description
This security bulletin contains information about 1 security vulnerability.
1) Cryptographic issues (CVE-ID: CVE-2012-0884)
The vulnerability allows a remote non-authenticated attacker to gain access to sensitive information.
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.
