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 known as
"SLOTH".

Affected Products and Versions
IBM Tivoli Security Policy Manager, versions 7.0 and 7.1
Remediation/Fixes
IBM Tivoli Security Policy Manager (TSPM) is affected through IBM WebSphere
Application Server. If you are running TSPM with one of the affected versions
of WebSphere, update your IBM WebSphere Application Server SDK with the
appropriate Interim Fix based on information in the WebSphere security
bulletin
(Security Bulletin: Multiple vulnerabilities in IBM Java SDK affect WebSphere
Application Server January 2016 CPU (CVE-2016-0475, CVE-2016-0466,
CVE-2015-7575, CVE-2016-0448)).
Product Version WebSphere version

WAS 7.0
WAS 8.0
TSPM 7.0 WAS 6.1
WAS 7.0
Workarounds and Mitigations
For CVE-2015-7575:
Users of Java 7 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 requires code changes in the JSSE component in addition to the
java.security file modifications, so upgrading the JDK is the only solution.
