Affected Products and Versions


For fixes, please consult the Multiple vulnerabilities in IBM® Java SDK affect WebSphere Application Server January 2016 CPU security bulletin for the following releases:

Principal Product and Version(s)Affected Supporting Product and Version
IBM Tivoli Network Manager 3.8Bundled the TIP version 1.1.1.x, which bundles IBM WebSphere version 6.1.0.x.
Note: "IBM highly recommends upgrading from Tivoli Network Manager v3.8, ideally to the latest release, which is currently v4.2. This is due to potential security risks with Tivoli Network Manager IP Edition v3.8. Tivoli Network Manager IP Edition v3.8 includes WebSphere Application Server 6.1 which uses Java 5.  The Java 5 release is no longer supported and as a result there will be no further security fixes made available for it."
IBM Tivoli Network Manager 3.9Bundled the TIP version 2.1.0.x, which bundles IBM WebSphere version 7.0.0.x.
IBM Tivoli Network Manager 4.1 and 4.1.1Bundled the TIP version 2.2.0.x, which bundles IBM WebSphere version 7.0.0.x.

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.
