Security Bulletin: Multiple vulnerabilities in the IBM GSKit and IBM GSKit-Crypto affect IBM Performance Management products

Summary

Multiple vulnerabilities in the IBM GSKit and IBM GSKit-Crypto affect IBM Performance Management products.

Vulnerability Details

CVEID: CVE-2018-1447
DESCRIPTION: The GSKit CMS KDB logic fails to salt the hash function resulting in weaker than expected protection of passwords. A weak password may be recovered. Note: After update the customer should change password to ensure the new password is stored more securely. Products should encourage customers to take this step as a high priority action.
