Who is Vulnerable?
Vulnerability Description	Computer Associates BrightStor ARCserve Backup products offer data protection for distributed servers, clients, databases and applications. They provide centralized control over a series of distributed operations including Backup and Restore, Data Migration, and Threat Management. There exists a buffer overflow vulnerability in the Computer Associates BrightStor ARCserve Backup product. The vulnerability is due to insufficient bounds checking in the user supplied data contained inside the requests sent to the caloggerd service. A remote unauthenticated attacker may leverage this vulnerability to inject and execute arbitrary code on the target host with System level privileges. In case of an attack where code injection is not successful the affected service will terminate abnormally. In case of a more sophisticated attack, where code injection is successful, the behaviour of the target host 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 service process. On Windows systems, the affected service is running with System privileges, by default configuration.
