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)

Workarounds and Mitigations
For CVE-2015-7575:
Users of Java 7 and later 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 modifications, so upgrading the JDK is the only solution.
