multiple flaws : 
 
  - A vulnerability in 'vserver' process could allow an 
    unauthenticated attacker to execute arbitrary code,
    subject to the privileges of the user under which the 
    process operates. In order to successfully exploit this 
    issue an attacker must have prior knowledge of an active 
    database name on the server. (CVE-2008-0307)

  - A design error in 'sdbstarter', could allow an attacker 
    to elevate his privileges to root level privileges.
    (CVE-2008-0306)

  - A vulnerability in cons.exe could allow command 
    execution before authenticating to the database server.
