Summary

GSKit is an IBM component that is used by IBM Rational RequisitePro. The GSKit
that is shipped with IBM Rational RequisitePro contains multiple security 
vulnerabilities including the FREAK: Factoring Attack on RSA-EXPORT keys" 
TLS/SSL client and server vulnerability. IBM Rational RequisitePro has 
addressed the applicable CVEs.

Vulnerability Details

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.

CVSS Base Score: 4.3

CVSS Temporal Score: See 
http://exchange.xforce.ibmcloud.com/#/vulnerabilities/100691 for the current 
score

CVSS Environmental Score*: Undefined

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

Affected Products and Versions

Version				Status

7.1.4 through 7.1.4.7		Affected

7.1.3 through 7.1.3.14		Affected

7.1.1.x, 7.1.2.x (all versions) Affected

You are vulnerable if you configure Rational RequisitePro to use LDAP 
authentication with secure socket connections.

Remediation/Fixes

The fix is to first upgrade ReqPro to 7.1.2.17, 7.1.3.14, or 7.1.4.7. If 
installing 7.1.3.14 or 7.1.4.7, then a second step is required, installing a 
newer version of the GSKit component that fixes the vulnerability. Contact 
Rational Customer Support for a copy of the fix and the instructions to 
manually patch your system(s).

2) If upgrading to 7.1.3.14, or 7.1.4.7, then contact Rational Customer 
support for instructions to download and install the GSKit fix. If you are 
upgrading to 7.1.2.17, then you are done.

You should verify applying this fix does not cause any compatibility issues.
