Security Bulletin: Multiple vulnerabilities in IBM Java SDKs affect IBM Virtualization Engine TS7700 - April 2015

Summary

There are multiple vulnerabilities in IBM® SDKs Java™ Technology Edition, Versions 5, 6 and 7, that are used by IBM Virtualization Engine TS7700. These issues were disclosed as part of the IBM Java SDK updates in April 2015. This bulletin also addresses the RC4 Bar Mitzvah Attack for SSL/TLS vulnerability.

Vulnerability Details

CVEID: CVE-2015-0488**
DESCRIPTION:** An unspecified vulnerability in Oracle Java SE and Jrockit related to the JSSE component could allow a remote attacker to cause a denial of service.
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-2015-0478**
DESCRIPTION:** An unspecified vulnerability in Oracle Java SE and JRockit related to the JCE component could allow a remote attacker to obtain sensitive information.
CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/102339 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N)

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
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)

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://xforce.iss.net/xforce/xfdb/99707 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

Remediation/Fixes

Contact IBM Service at 1-800-IBM-SERV to arrange an upgrade to the latest microcode level followed by the installation of vtd_exec.213, vtd_exec.214 and vtd_exec.215 as needed. Minimum microcode levels are shown below:

Release

| Fix
—|—
R3.0, R3.1 or R3.2| Upgrade to 8.32.1.8 or later + vtd_exec.213 + vtd_exec.214 + vtd_exec.215
R2.1| Upgrade to 8.21.0.178 or later + vtd_exec.213 + vtd_exec.214 + vtd_exec.215
Older Releases| Upgrade to 8.21.0.178 or later + vtd_exec.213 + vtd_exec.214 + vtd_exec.215

Workarounds and Mitigations

Although IBM recommends that you upgrade to the fixes identified above, you can mitigate, but not eliminate the risk of these vulnerabilities by restricting physical and network access to the TS7700 to authorized users and IBM Service Personnel only.
