Summary

Security vulnerabilities that affect ICU, that is embedded in IBM Cognos Analytics, have been addressed.

Cognos Analytics consumes Bootstrap and Jcraft Jsch. The versions of these components have been upgraded to addressed known vulnerabilities.

A vulnerability has been addressed in which IBM Cognos Analytics could be vulnerable to a DOS attack.

A stored XSS vulnerability has been addressed which could allow users to embed arbitrary JavaScript code in the Web UI thus altering the intended functionality potentially leading to credentials disclosure within a trusted session.

Vulnerability Details

CVEID: CVE-2017-15422 DESCRIPTION: Integer overflow in international date handling in International Components for Unicode (ICU) allowed a remote attacker to perform an out of bounds memory read via a crafted HTML page.
CVSS Base Score: 6.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/136054&gt; for the current score
CVSS Environmental Score*: Undefined
