Summary
The Logjam Attack on TLS connections using the Diffie-Hellman (DH) key exchange protocol affects Tivoli Storage Productivity Center.
UPDATED 1/29/2018: Even after fixing this vulnerability some vulnerability checks might still demand for an even tighter fix. A more comprehensive fix has been provided in IBM Spectrum Control.
Vulnerability Details
- CVEID: CVE-2015-4000
DESCRIPTION: The TLS protocol could allow a remote attacker to obtain sensitive information, caused by the failure to properly convey a DHE_EXPORT ciphersuite choice.
