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.
