Vulnerability Details CVE ID: CVE-2014-0411 DESCRIPTION: Timing differences based on the validity of messages can be exploited to decrypt the entire session. The exploit is not trivial, requiring a man-in-the-middle position and a long time (around 20 hours). The fix eliminates the timing differences. CVSS: CVSS Base Score: 4 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/90357 CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:H/Au:N/C:P/I:P/A:N) CVE ID: CVE-2013-4322 DESCRIPTION: Apache Tomcat before 6.0.39, 7.x before 7.0.50, and 8.x before 8.0.0-RC10 processes chunked transfer coding without properly handling (1) a large total amount of chunked data or (2) whitespace characters in an HTTP header value within a trailer field, which allows remote attackers to cause a denial of service by streaming data. NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-3544. CVSS: CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91625 CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) CVE ID: CVE-2013-4286 DESCRIPTION: Apache Tomcat before 6.0.39, 7.x before 7.0.47, and 8.x before 8.0.0-RC3, when an HTTP connector or AJP connector is used, does not properly handle certain inconsistent HTTP request headers, which allows remote attackers to trigger incorrect identification of a request's length and conduct request-smuggling attacks via (1) multiple Content-Length headers or (2) a Content-Length header and a Transfer-Encoding: chunked header. NOTE: this vulnerability exists because of an incomplete fix for CVE-2005-2090. CVSS: CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91426 CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) Affected Products and Versions IBM Cognos Business Viewpoint 10.1.1 IBM Cognos Business Viewpoint 10.1 IBM Cognos Business Viewpoint 8.4.1 Remediation/Fixes The recommended solution is to apply the fix in one of the 10.1.x versions listed or in version 8.4.1 for your release version as soon as practical.
