OpenSSL vulnerabilities were disclosed on January 8, 2015 by the OpenSSL Project. This includes “FREAK: Factoring Attack on RSA-EXPORT keys” TLS/SSL client and server vulnerability. OpenSSL is used by Integrated Management Module II (IMM2). IMM2 has addressed the applicable CVEs.
Vulnerability Details:
CVE-ID: 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 Base Score: 4.3
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/99707> for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2014-3569
Description: OpenSSL is vulnerable to a denial of service, caused by the failure to properly handle attempts to use unsupported protocols by the ssl23_get_client_hello function in s23_srvr.c. A remote attacker could exploit this vulnerability using an unexpected handshake to trigger a NULL pointer dereference and cause the daemon to crash.

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE-ID: 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 Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2014-3571
Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when handling malicious messages. By sending a specially-crafted DTLS message, a remote attacker could exploit this vulnerability to cause a segmentation fault.
CVSS Base Score: 5
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/99703> for current score

CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVE-ID: 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 <http://xforce.iss.net/xforce/xfdb/99705> for current score

CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2014-8275
Description: OpenSSL could allow a local attacker to bypass security restrictions, caused by the modification of the fingerprint without breaking the signature. An attacker could exploit this vulnerability using non-DER or invalid encodings outside the signed portion of a certificate bypass security restrictions and perform unauthorized actions.
CVSS Base Score: 1.2

CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2015-0205
Description: OpenSSL could allow a remote authenticated attacker to bypass security restrictions, caused by the acceptance of a DH certificate for client authentication without verification. An attacker could exploit this vulnerability to authenticate without the use of a private key.
CVSS Base Score: 2.1
CVSS Temporal Score: See <http://xforce.iss.net/xforce/xfdb/99708> for current score

CVSS Vector: (AV:N/AC:H/Au:S/C:N/I:P/A:N)
CVE-ID: CVE-2015-0206
Description: OpenSSL is vulnerable to a denial of service, caused by a memory leak in the dtls1_buffer_record function. By sending repeated DTLS records with the same sequence number, a remote attacker could exploit this vulnerability to exhaust all available memory resources.

All IMM2 firmware releases prior to v4.90 for these systems:
Firmware updates are available at IBM Fix Central - <http://www.ibm.com/support/fixcentral/> .
It is recommended to update the following affected systems to Integrated Management Module 2 v4.97 (1AOO66M) or above:
It is recommended to update the following affected systems to Integrated Management Module 2 v4.90 (1AOO66O) or above:
You can avoid CVE-2015-0204, also referred to as FREAK, on the IMM2 by disabling export-grade ciphers on any server the IMM2 may connect to, such as your LDAP server.
You should verify applying this configuration change does not cause any compatibility issues.
