Vulnerability Details
CVEID:
CVE-2016-0466
DESCRIPTION:
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: 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-2015-4872
DESCRIPTION:
An unspecified vulnerability in Oracle Java SE and JRockit related to the
Security component has no confidentiality impact, partial integrity impact,
and no availability impact.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/107361
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/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.
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/S:U/C:H/I:L/A:N)

Workarounds and Mitigations
To address CVE-2015-7575, users that are on Java 7 or Java 8 can update the
/jre/lib/security/java.security file as follows (both steps are required):
Add MD5 to the jdk.certpath.disabledAlgorithms property - for example,
jdk.certpath.disabledAlgorithms=MD2, RSA keySize < 1024, MD5
Add MD5withRSA to the jdk.tls.disabledAlgorithms property - for example,
jdk.tls.disabledAlgorithms=SSLv3, RC4, DH keySize < 768, MD5withRSA
