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”.

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.
