Security Bulletin: IBM Verify Gateway does not hide client secrets when debug tracing is active (CVE-2020-4372)

Summary

When the IBM Verify Gateway (IVG) components are run with debug tracing, client secrets such as the username, password, and client-id are included in the debug log. As of v1.0.1 of IVG for RADIUS and IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM and IVG for Windows Login, these client secrets are suppressed when debug tracing is active.
