Details
Ivan Nestlerode discovered that the Cryptographic Message Syntax
(CMS) and PKCS #7 implementations in OpenSSL returned early if RSA
decryption failed. This could allow an attacker to expose sensitive
information via a Million Message Attack (MMA). (CVE-2012-0884)
It was discovered that an integer underflow was possible when using
TLS 1.1, TLS 1.2, or DTLS with CBC encryption. This could allow a
remote attacker to cause a denial of service. (CVE-2012-2333)
