Summary

The OpenSSL library used in IBM Campaign and Contact Optimization is 
vulnerable to TLS protocol downgrade attack.

Vulnerability Details

CVEID: 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.

CVSS Base Score: 4.3
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95162
