The IBM Verify Gateway (IVG) PAM components include a leftover header file in their installation packages. The file was needed for debugging during development and shouldn't be part of the delivered PAM components. As of v1.0.1 of IVG for AIX PAM, and v1.0.2 of IVG for Linux PAM, the file has been removed from the installation packages.
DESCRIPTION: IBM Verify Gateway (IVG) contains sensitive information in leftover debug code that could be used aid a local user in further attacks against the system.
