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 Environmental Score*: Undefined
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 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".
CVSS Base Score: 5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/101851 for the current score
CVSS Environmental Score*: Undefined

Workarounds and Mitigations

Mitigation for CVE-2015-2808 on IBM SDK, Java Technology Edition, Version 7, 7R1 and 8:

  • Disable RC4 cipher suites by adding "RC4" to the list of disabled algorithms defined by the jdk.tls.disabledAlgorithms security property in the java.security file.

No equivalent mitigation is available for IBM SDK, Java Technology Edition, Version 6, and IBM SDK, Java 2 Technology Edition, Version 5.0. For these versions the code fix must be applied.
