Security Bulletin: Vulnerabilities in OpenSSL affect IBM Sterling 
Connect:Direct for UNIX (CVE-2014-3570, CVE-2015-0204, CVE-2015-0205)

Security Bulletin

Document information

More support for:

Sterling Connect:Direct for UNIX

Software version:

4.0, 4.1

Operating system(s):

AIX, HP-UX, Linux, Solaris

Reference #:

1700202

Modified date:

2015-03-27

Summary

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 IBM Sterling 
Connect:Direct for UNIX. IBM Sterling Connect:Direct for UNIX has 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 
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-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)

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

CVEID: CVE-2015-0138

DESCRIPTION: A vulnerability in various IBM SSL/TLS implementations could 
allow a remote attacker to downgrade the security of certain SSL/TLS 
connections. An IBM SSL/TLS client implementation could accept 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.
