Vulnerability CVE-2016-0391

Vulnerability Name:

CVE-2016-0391 (CCN-112560)

Assigned:

2015-12-08

Published:

2016-05-11

Updated:

2016-07-07

Summary:

The IBM Watson Developer Cloud services on Bluemix platforms do not properly generate random numbers for service-instance credentials, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a brute-force attack.
