Vulnerability Details
CVEID: CVE-2016-0475DESCRIPTION: An unspecified vulnerability in Oracle Java SE Java SE Embedded and Jrockit related to the Librariesc component has partial confidentiality impact, partial integrity impact, and no availability impact.CVSS Base Score: 5.8CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109946 for the current scoreCVSS Environmental Score*: UndefinedCVSS Vector: (AV:N/AC:M/Au:N/C:P/I:P/A:N)
CVEID: CVE-2016-0466DESCRIPTION: An unspecified vulnerability in Oracle Java SE Java SE Embedded and Jrockit related to the JAXP component could allow a remote attacker to cause a denial of service resulting in a partial availability impact using unknown attack vectors.CVSS Base Score: 5CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109948 for the current scoreCVSS Environmental Score*: UndefinedCVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-7575DESCRIPTION: 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.CVSS Base Score: 7.1CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109415 for the current scoreCVSS Environmental Score*: UndefinedCVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N)
CVEID: CVE-2016-0448DESCRIPTION: An unspecified vulnerability in Oracle Java SE and Java SE Embedded related to the JMX component could allow a remote attacker to obtain sensitive information resulting in a partial confidentiality impact using unknown attack vectors.CVSS Base Score: 4CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109949 for the current scoreCVSS Environmental Score*: UndefinedCVSS Vector: (AV:N/AC:L/Au:S/C:P/I:N/A:N)
Affected Products and Versions

Remediation/Fixes
Workarounds and Mitigations
For CVE-2015-7575:
Users of Java 7 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 modification, so upgrading the JRE is the only solution.
