These issues were disclosed as part of the IBM Java SDK updates in January 2016 and includes the vulnerability commonly referred to as SLOTH. Vulnerability Details CVEID: CVE-2016-0475 DESCRIPTION: An unspecified vulnerability related to the Libraries component has partial confidentiality impact, partial integrity impact, and no availability impact. CVSS Base Score: 5.8 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109946 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N) CVEID: CVE-2016-0466 DESCRIPTION: An unspecified vulnerability related to the JAXP component could allow a remote attacker to cause a denial of service. CVSS Base Score: 5 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109948 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVEID: CVE-2015-7575 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) CVEID: CVE-2016-0448 DESCRIPTION: An unspecified vulnerability related to the JMX component could allow a remote attacker to obtain sensitive information. CVSS Base Score: 4 CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109949 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N) Affected Products and Versions This vulnerability affects IBM Integration Designer and WebSphere Integration Developer. Remediation/Fixes To fully mitigate these vulnerabilities, an additional fix (JR55223) is required for the following product versions: WebSphere Integration Developer V7.0.0.x IBM Integration Designer V7.5.1.2 IBM Integration Designer V8.0.1.3 IBM Integration Designer V8.5.0.1 IBM Integration Designer V8.5.5.0 IBM Integration Designer V8.5.6.0 Workarounds and Mitigations For CVE-2015-7575: For IBM Integration Designer V8.5.0.0 and higher, CVE-2015-7575 can be addressed by updating the /jre/lib/security/java.security file as follows (both steps are required): 1. Add MD5 to the jdk.certpath.disabledAlgorithms property, for example, jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024, MD5 2. Add MD5withRSA to the jdk.tls.disabledAlgorithms property, for example, jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA For versions of IBM Integration Designer earlier than V8.5.0.0 and for WebSphere Integration Developer V7.0.0.x, 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.
