       Backup Software (EBS)
     * Category: Security
     * Product: Sun StorEdge Enterprise Backup Software 7.2, Sun StorEdge
       Enterprise Backup Software 7.0, Solstice Backup 6.0, Solstice
       Backup 6.1, Sun StorEdge Enterprise Backup Software 7.1

1. Impact

   There are three vulnerabilities in Sun StorEdge Enterprise Backup
   Software (EBS), which affect both the client and server applications.
   Two of the vulnerabilities could permit a local or remote unauthorized
   user to gain access to a host system and execute arbitrary code. One
   may allow a local or remote unauthenticated user to cause a system
   crash on the server, which would lead to a Denial of Service (DoS)
   condition.

   Note: To date there are no reported incidences of this issue having
   occurred in a "live" (public) environment.

   These issues are referenced in the following iDEFENSE
   (http://www.idefense.com) documents:
