Description: Compaq reported a potential vulnerability with the Compaq ACMS application for OpenVMS. A local user may be able to obtain elevated privileges on the system.
Compaq reports that OpenVMS Alpha may have a potential security vulnerability in its processing of ACMS process privileges. This
