Who is Vulnerable?
Vulnerability Description	There exists a buffer overflow vulnerability in CA BrightStor ARCserve Backup Message Engine. The vulnerability is due to insufficient boundary checking when processing strings supplied in RPC requests. Successful exploitation of this vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the vulnerable system in the context of the affected application, commonly System. In an attack case where code injection is not successful, the affected service will terminate unexpectedly. This will create a denial of service condition of the affected service. In a more sophisticated attack where code injection results in successful process flow diverting, the behavior of the target is entirely dependent on the intended function of the injected code. The code in such a case would execute within the security context of the running process, normally System.
