   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.

   2. Contributing Factors These issues can occur in the following
   release on all platforms:
