Security Bulletin
Summary
There are multiple vulnerabilities in IBM Runtime Environment Java Technology
Edition, Versions 1.6 and 1.7 that is used by IBM SPSS Statistics. These
issues were disclosed as part of the IBM Java SDK updates in October 2015 and
includes the vulnerability commonly referred to as SLOTH.
Vulnerability Details
CVEID: CVE-2015-4872
DESCRIPTION: An unspecified vulnerability in Oracle Java SE and JRockit
related to the Security component has no confidentiality impact, partial
integrity impact, and no availability impact.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/107361 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:P/A:N)
CVEID: CVE-2015-4734
DESCRIPTION: An unspecified vulnerability in Oracle Java SE related to the
JGSS component could allow a remote attacker to obtain sensitive information.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/107356 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:N/A:N)
CVEID: CVE-2015-5006
DESCRIPTION: IBM Java Security Components could allow an attacker with
physical access to the system to obtain sensitive information from the
Kerberos Credential Cache.
CVSS Base Score: 4.6
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/106309 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID: CVE-2015-7575
DESCRIPTION: The TLS protocol could allow weaker than expected security caused
by a collision attack when using the MD5 hash function for signing a
ServerKeyExchange message during a TLS handshake. An attacker could exploit
this vulnerability using man-in-the-middle techniques to impersonate a TLS
server and obtain credentials. This vulnerability is commonly referred to as
SLOTH.
CVSS Base Score: 7.1
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/109415 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/UI:U/C:H/I:L/A:N)

Workarounds and Mitigations
For CVE-2015-7575:
Users of Java 7 (SPSS Statistics 23) and later can address the issue by
updating the /jre/lib/security/java.security file as follows (both steps are
required):
Add MD5 to the jdk.certpath.disabledAlgorithms property - e.g.
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024, MD5
Add MD5withRSA to the jdk.tls.disabledAlgorithms property - e.g.
jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA
Java 6 (SPSS Statistics 19 thru 22) requires code changes in the JSSE
component in addition to the java.security file modifications, so upgrading
the JDK is the only solution.
