CVEID: CVE-2015-0204**
DESCRIPTION:** A vulnerability in the OpenSSL ssl3_get_key_exchange function could allow a remote attacker to downgrade the security of certain TLS connections. An OpenSSL client accepts the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers. This vulnerability is also known as the FREAK attack.

CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-0192**
DESCRIPTION:** A vulnerability in the IBM implementation of the Java Virtual Machine may, under limited circumstances, allow untrusted code running under a security manager to elevate its privileges.
CVSS Base Score: 6.8
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/101008&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:P)

CVEID: CVE-2015-2808**
DESCRIPTION:** The RC4 algorithm, as used in the TLS protocol and SSL protocol, could allow a remote attacker to obtain sensitive information. An attacker could exploit this vulnerability to remotely expose account credentials without requiring an active man-in-the-middle session. Successful exploitation could allow an attacker to retrieve credit card data or other sensitive information. This vulnerability is commonly referred to as “Bar Mitzvah Attack”.
