| Vendor threat level | Important
|
| SophosLabs threat level | Low
|
| Solution | MS11-082
|
| Vendor description | This security update resolves two publicly disclosed vulnerabilities in Host Integration Server. The vulnerabilities could allow denial of service if a remote attacker sent specially crafted network packets to a Host Integration Server listening on UDP port 1478 or TCP ports 1477 and 1478. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed. In this case, the Host Integration Server ports should be blocked from the Internet.
|
| SophosLabs comments | Users can mitigate this vulneratility by blocking TCP ports 1477 and 1478 and UDP port 1478 at their firewall.
|
| SophosLabs testing result | |
| Currently known exploits | At the time of writing SophosLabs have not observed any malware attempting to exploit this vulnerability. Should this situation change samples will be analyzed and we will take action as necessary.
