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

CVEID: CVE-2015-1931

DESCRIPTION: IBM Java Security Components store plain text data in memory
dumps, which could allow a local attacker to obtain information to aid in
further attacks against the system.

CVSS Base Score: 2.1
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/102967 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:L/Au:N/C:P/I:N/A:N)

CVEID: CVE-2015-1916

DESCRIPTION: Server applications which use the IBM Java Secure Socket
Extension provider to accept SSL/TLS connections are vulnerable to a denial
of service attack due to an unspecified vulnerability.

CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/101995 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVEID: CVE-2015-0488

DESCRIPTION: Server applications which use the IBM Java Secure Socket
Extension provider to accept SSL/TLS connections are vulnerable to a denial
of service attack due to an unspecified vulnerability.

CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/102336 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)


CVEID: CVE-2015-2808

Description: The RC4 algorithm, as used in the TLS protocol and SSL protocol,
could allow a remote attacker to obtain sensitive information. An attacker
could exploit this vulnerability to remotely expose account credentials
without requiring an active man-in-the-middle session. Successful
exploitation could allow an attacker to retrieve credit card data or
other sensitive information. This vulnerability is commonly referred to as
"Bar Mitzvah Attack".

CVSS Base Score: 5.0
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/101851 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)

For more details, refer the technote at 1702789

CVEID: CVE-2015-4000

DESCRIPTION: The TLS protocol could allow a remote attacker to obtain
sensitive information, caused by the failure to properly convey a DHE_EXPORT
ciphersuite choice. An attacker could exploit this vulnerability using
man-in-the-middle techniques to force a downgrade to 512-bit export-grade
cipher. Successful exploitation could allow an attacker to recover the
session key as well as modify the contents of the traffic. This vulnerability
is commonly referred to as "Logjam".

CVSS Base Score: 4.3
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/103294 for the
current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

For more details, refer the technote at 1959284

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

Remediation/Fixes

Replace the JRE used in IBM RLKS Administration and Reporting Tool and
IBM RLKS Administration Agent.
Steps to replace the JRE in IBM RLKS Administration and Reporting Tool
(All Versions)

1. Go to Fix Central

2. On the Find product tab, enter Rational Common Licensing in the Product
Selector field and hit enter.

3. Select the Installed Version and hit continue button.

4. Select the platform of the machine where RLKS Administration and
Reporting Tool is installed and hit continue button.

5. On the Identify fixes page, select Browse for fixes and select Show
fixes that apply to this version and hit continue button.

6. Download the Java runtime iFix for RLKS Administration and Reporting Tool.

Note: Although the name of the iFix is
RLKS_Administration_And_Reporting_Tool_8148_Admin_iFix_1_<Platform>_<Architecture>,
the same ifix is applicable to all previous RLKS Administration and
Reporting Tool versions.

7. Shutdown RLKS Administration and Reporting Tool.

8. Go to the installation location of RLKS Administration and Reporting Tool.

9. Rename <install location>/server/jre folder to <install
location>/server/jre_back.
This step backs up the existing JRE.

10. Extract the downloaded JRE into <install location>/server/ folder

Example: <install location>/server/jre

11. Startup RLKS Administration and Reporting Tool.

12. Login to the tool using rcladmin user and verify that you see the
configured license servers under 'Server' tab.
