CVEID: CVE-2016-5597
DESCRIPTION: An unspecified vulnerability related to the Networking component could allow a remote attacker to obtain sensitive information resulting in a high confidentiality impact using unknown attack vectors.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/118071 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2016-5548
DESCRIPTION: An unspecified vulnerability related to the Libraries component could allow a remote attacker to obtain sensitive information resulting in a high confidentiality impact using unknown attack vectors.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/120864 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N)
CVEID: CVE-2016-5549
DESCRIPTION: An unspecified vulnerability related to the Libraries component could allow a remote attacker to obtain sensitive information resulting in a high confidentiality impact using unknown attack vectors.
CVSS Base Score: 6.5
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/120863 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N)
CVEID: CVE-2016-5547
DESCRIPTION: An unspecified vulnerability related to the Libraries component could allow a remote attacker to cause a denial of service resulting in a low availability impact using unknown attack vectors.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/120871 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-2183
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in the DES/3DES cipher, used as a part of the SSL/TLS protocol. By capturing large amounts of encrypted traffic between the SSL/TLS server and the client, a remote attacker able to conduct a man-in-the-middle attack could exploit this vulnerability to recover the plaintext data and obtain sensitive information. This vulnerability is known as the SWEET32 Birthday attack.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/116337 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
Affected Products and Versions
IBM Rational Synergy 7.2.1 – 7.2.1.5.x
IBM Rational Synergy 7.2.0 – 7.2.0.7.x
Remediation/Fixes
|
Product | VRMF | APAR | Remediation/First Fix |
| Rational Synergy | 7.2.0.x and 7.2.1.x | N/A | Replace the JRE used in Rational Synergy. Steps to download and replace JRE in Rational Synergy: 1. Open the list of Synergy downloads on Fix Central 2. Select the SDK and Readme for Rational Synergy which applied to your release as follows: Note: The fix will use the following naming convention: <V.R.M.F> -Rational-RATISYNE-JavaSE-SDK-6.0.16.41- <platform> Where <V.R.M.F> = release & <platform> = operating system o Rational Synergy 7.2.1 (uses 7.2.1.5 release designation) Example: 7.2.1.5-Rational-RATISYNE-JavaSE-SDK-6.0.16.41-Linux o Rational Synergy 7.2.0 (uses 7.2.0.7 release designation) Example: 7.2.0.7-Rational-RATISYNE-JavaSE-SDK-6.0.16.41-Windows 3. Follow the steps in the Install instructions to replace the JRE. Follow the steps in the HPUX_Install Instructions to replace the JRE if your Synergy Platform is on HPUX |
To verify if Synergy has JRE version to address these security vulnerabilities:-
Open a command prompt
Unix:-
Go to $CCM_HOME/jre/bin folder
Execute ./java -version
Windows:-
Go to %CCM_HOME%\jre\bin folder
Execute java -version
If the output version is SR16 FP40 or greater than SR16 FP40, it implies the run area has jre version that addresses these security vulnerabilities.
Example:-
java version "1.6.0"
Java(TM) SE Runtime Environment (build pxi3260sr16fp20-20160111_01(SR16 FP20))
IBM J9 VM (build 2.4, JRE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260sr16fp20-20151221_282799 (JIT enabled, AOT enabled)
