These issues were disclosed as part of the IBM Java SDK updates in January 2016. Vulnerability Details 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) CVEID: CVE-2016-0475 DESCRIPTION: An unspecified vulnerability 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-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) Affected Products and Versions FileNet Content Manager 5.1.0, 5.2.0, 5.2.1 IBM Content Foundation 5.2.0, 5.2.1 FileNet Business Process Manager 4.5.1, 5.0.0 FileNet eProcess 5.2.0 Remediation/Fixes Install one of the fixes listed below to upgrade the Java JRE. The fixes listed in the table below supply the proper Java JRE for the various release levels of the affected products. Depending upon the product and release level, these fixes will upgrade the Java JRE to one of: IBM JRE, Java Technology Edition, Version 6 Service Refresh 16 Fix Pack 20 IBM JRE, Java Technology Edition, Version 7 Service Refresh 9 Fix Pack 30 IBM JRE, Java Technology Edition, Version 8 Service Refresh 2 Fix Pack 10 Product VRMF APAR Remediation/First Fix FileNet Content Manager 5.1.0 PJ43917 126.96.36.199-P8CSS-IF015 - 2/23/2016 5.2.0 PJ43915 188.8.131.52-P8CPE-IF003 - 2/23/2016 5.2.1 PJ43915 184.108.40.206-P8CPE-IF001 - 2/23/2016 PJ43998 220.127.116.11-P8CSS-IF001 - 3/21/2016 IBM Content Foundation 5.2.0 PJ43915 18.104.22.168-P8CPE-IF003 - 2/23/2016 5.2.1 PJ43915 22.214.171.124-P8CPE-IF001 - 2/23/2016 FileNet Business Process 4.5.1 PJ43908 126.96.36.199-P8PE-IF010 - 2/23/2016 Manager 5.0.0 PJ43914 188.8.131.52-P8PE-IF003 - 2/23/2016 FileNet eProcess 5.2.0 PJ43916 eProcess-5.2.0-001.008 - 2/23/2016 In the above table, the APAR links will provide more information about the fix. The links in the Remediation column will take you to the location within IBM Fix Central where you can download the particular fix you need. Workarounds and Mitigations The new JREs that are supplied by the above fixes resolve the CVE-2015-7575 (SLOTH) vulnerability. Note that CSS 5.1 uses Java 6 and has issued a patch. CSS 5.2.0 and CSS 5.2.1 use Java 8 and are not issuing a patch at this time because the vulnerability can be eliminated as follows: 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 Note: If you install a Java fix pack, that will overwrite the above java.security file changes.
