Security Bulletin: IBM Cognos Business Intelligence Server 2016Q1 Security Updater : IBM Cognos Business Intelligence Server is affected by multiple vulnerabilities.

Description

## Summary This bulletin addresses several security vulnerabilities. There are multiple vulnerabilities in IBM® Runtime Environment Java™ Technology Edition, Version 6 and the IBM® Runtime Environment Java™ Technology Edition, Version 7 that are used by IBM Cognos Business Intelligence. These issues were disclosed as part of the IBM Java SDK updates in January 2016. Security issues were also addressed in LibXML2 and IBM WebSphere Portal (Liberty Profile). Due to the ending of support for OpenSSL 0.9.8 we have upgraded to OpenSSL 1.0.2e If you are using IBM Cognos TM1, you should also apply IBM Cognos TM1 Security fixes. This will ensure TM1 and Business Intelligence continue to operate as expected. Please see the Related Information section below. ## Vulnerability Details **CVEID**: [CVE-2015-1819](<https://vulners.com/cve/CVE-2015-1819>) **DESCRIPTION**: Libxml is vulnerable to a denial of service, caused by an XML External Entity Injection (XXE) error in the xmlreader when processing XML data. A remote attacker could exploit this vulnerability to consume all available memory resources. CVSS Base Score: 5.300 CVSS Temporal Score: <https://exchange.xforce.ibmcloud.com/vulnerabilities/107272> for more information CVSS Environmental Score*: Undefined CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L) **CVEID**: [CVE-2015-2017](<https://vulners.com/cve/CVE-2015-2017>) **DESCRIPTION**: The IBM WebSphere Portal is vulnerable to HTTP response splitting attacks.
