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.
