Security Bulletin: Vulnerabilities in OpenSSL affect the Cordova platform packaged with Rational Application Developer affecting Rational Developer for i and Rational Developer for AIX and Linux

Summary

Portions of IBM Rational Application Developer for WebSphere Software are shipped as a component of Rational Developer for i (RPG and COBOL + Modernization Tools, Java and EGL editions), and Rational Developer for AIX and Linux.
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 the Cordova platform packaged with Rational Application Developer for WebSphere Software and has addressed the applicable CVEs (CVE-2014-3570, CVE-2014-3571, CVE-2014-3572, CVE-2014-8275, CVE-2015-0204, CVE-2015-0205, CVE-2015-0206).

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 http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99710 or the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)

CVEID: 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://exchange.xforce.ibmcloud.com/#/vulnerabilities/99703 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

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 http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99705 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)

CVEID: 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 Temporal Score: See http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99709 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: 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://exchange.xforce.ibmcloud.com/#/vulnerabilities/99707 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVEID: 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://exchange.xforce.ibmcloud.com/#/vulnerabilities/99708 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:S/C:N/I:P/A:N)

CVEID: 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
CVSS Base Score: 5
CVSS Temporal Score: See http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99704 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
