IBM Worklight and IBM MobileFirst Platform Foundation have addressed the applicable CVEs.

Vulnerability Details

CVEID: CVE-2014-3570**
DESCRIPTION:** An unspecified error in OpenSSL related to the production of incorrect results on some platforms by Bignum squaring (BN_sqr) has an unknown attack vector and impact.
CVSS Base Score: 2.6
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/99710&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)

CVEID: CVE-2014-3572**
DESCRIPTION:** OpenSSL could provide weaker than expected security. The client accepts a handshake using an ephemeral ECDH ciphersuite with the server key exchange message omitted. An attacker could exploit this vulnerability to launch further attacks on the system.
CVSS Base Score: 1.2
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/99705&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)

CVEID: CVE-2015-0204**
DESCRIPTION:** OpenSSL could allow a remote attacker to bypass security restrictions, caused by an error in the ssl3_get_key_exchange function. The client accepts the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. An attacker could exploit this vulnerability using man-in-the-middle techniques to facilitate brute-force decryption.
CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/99707&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
