Vulnerability Details
CVEID: CVE-2016-0475
DESCRIPTION: An unspecified vulnerability in Oracle Java SE Java SE Embedded and Jrockit 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-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”.

Affected Products and Versions
WebSphere eXtreme Scale 7.1.0
WebSphere eXtreme Scale 7.1.1
WebSphere eXtreme Scale 8.5
WebSphere eXtreme Scale 8.6
Remediation/Fixes
Since MD5 signatures are no longer compatible with Java, installing this interim fix will make it incompatible with any WebSphere eXtreme Scale clients and servers that are running with an MD5 certificate. If any WebSphere eXtreme Scale clients or servers are configured with a certificate with an MD5 signature, they must be replaced prior to starting after upgrading to this interim fix. Failing to do so will result in the clients and servers failing to connect to each other. Note that client truststores must be configured to trust the new certificate.
| <Product | VRMF | APAR | Remediation/First Fix |
| WebSphere eXtreme Scale | 7.1 | PI56344 | Refer to the Version 7.1 table in the Recommended Fixes page for WebSphere eXtreme Scale. |
| WebSphere eXtreme Scale | 7.1.1
8.5 8.6 | PI56341 | Refer to the Version 7.1.1, 8.5, or 8.6 table in the Recommended Fixes page for WebSphere eXtreme Scale. |
Workarounds and Mitigations
No workaround exists. If you are running WebSphere eXtreme Scale standalone, apply the appropriate fix from the previous table. If you are running WebSphere eXtreme Scale clients or servers that are embedded in WebSphere Application Server, apply the appropriate fix for WebSphere Application Server, which is described here: https://www-304.ibm.com/support/docview.wss?uid=swg21962931
