Computer Associates BrightStor ARCserve Backup Discovery Service SERVICEPC vulnerable to buffer overflow

Vulnerability Note VU#966880

Original Release Date: 2005-08-04 | Last Revised: 2005-08-11


The Computer Associates BrightStor ARCserve Backup Discovery Service contains a buffer overflow, which may allow a remote attacker to execute arbitrary code.


Computer Associates BrightStor ARCserve Backup is a cross-platform backup and recovery application. The ARCserve Backup Discovery Service fails to properly check incoming network traffic on 41523/tcp, creating a buffer overflow vulnerability.

Exploit code for this vulnerability is publicly available.


A remote, unauthenticated attacker may be able to execute arbitrary code on a system running the vulnerable software.


Upgrade or patch
Upgrade or install patches, as recommended by the Computer Associates vulnerability 32478 description.

Restrict access

You may wish to block access to the vulnerable software from outside your network perimeter, specifically by blocking access to the ports used by the Discovery Service (typically 41523/tcp). This will limit your exposure to attacks. However, blocking at the network perimeter would still allow attackers within the perimeter of your network to exploit the vulnerability. The use of host-based firewalls in addition to network-based firewalls can help restrict access to specific hosts within the network. It is important to understand your network's configuration and service requirements before deciding what changes are appropriate.
