Vulnerability Details Watson Explorer is affected by the following vulnerabilities from the OpenSSL Security Advisory [6 Aug 2014] CVE-ID: CVE-2014-5139 DESCRIPTION: The issue affects OpenSSL clients and allows a malicious server to crash the client with a null pointer dereference (read) by specifying an SRP ciphersuite even though it was not properly negotiated with the client. This can be exploited through a Denial of Service attack. CVE-ID: CVE-2014-3509 DESCRIPTION: If a multithreaded client connects to a malicious server using a resumed session and the server sends an ec point format extension it could write up to 255 bytes to freed memory. CVE-ID: CVE-2014-3511 DESCRIPTION: A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate TLS 1.0 instead of higher protocol versions when the ClientHello message is badly fragmented. This allows a man-in-the-middle attacker to force a downgrade to TLS 1.0 even if both the server and the client support a higher protocol version, by modifying the client's TLS records. CVE-ID: CVE-2014-3512 DESCRIPTION: A malicious client or server can send invalid SRP parameters and overrun an internal buffer. Only applications which are explicitly set up for SRP use are affected. Affected Products and Versions Watson Explorer Version 9.0.0.4 and earlier. Remediation/Fixes Upgrade to IBM Watson Explorer 9.0.0.5. For all releases between 8.0 and 9.0.0.4, contact IBM Support. A hot fix is available which will upgrade the 0.9.8za OpenSSL libraries to version 0.9.8zb.
