    1. Impact Buffer overflow vulnerabilities in the Sun Java System Web
    Proxy Server may allow a remote unprivileged user to crash either the
    Web Proxy Server or the Admin Server (of the Web Proxy Server) or
    execute arbitrary code with the privileges of the respective server
    processes.

    Note: The recommended UIDs for the Web Proxy Server and Admin Server
    are "nobody" and "root" respectively, at installation time. However,
    the administrator may have used different UIDs from the recommended
    ones during installation.

    Sun acknowledges with thanks, Matt Moore of Pentest Limited, for
    bringing these issues to our attention.
