Details
The Intel Alert Management System (AMS2) is used in Symantec AntiVirus Corporate Edition Server (SAVCE), Symantec System Center (SSC), and Symantec Quarantine Server. AMS2 listens on TCP Port 38292 and allows SAVCE Administrators to send messages(i.e. email) if a user-specified event occurs.
Symantec was notified of multiple vulnerabilities in AMS2. It is possible to send specially-crafted packets to the targeted server, causing a buffer overflow or allowing arbitrary commands to run, potentially executing arbitrary code. The successful exploitation of these vulnerabilities could result in a possible compromise of the affected products.
AMS2 has not been included in a default install of SAVCE Server or SSC since version 10.0. AMS2 was included in the default install of Quarantine Server prior to SEP 11.0 MR3.
Symantec Response
Symantec engineers verified these issues and released an update to address them. Symantec customers should update to the latest maintenance release available through normal update procedures.
Symantec knows of no exploitation of or adverse customer impact from this issue.
Mitigations
Symantec recommends upgrading any vulnerable versions of SAVCE Server or Symantec System Center to SAVCE 10.1 MR10. Vulnerable versions of Quarantine Server 3.5 should be upgraded to SAVCE 10.1 MR10. Vulnerable versions of Quarantine Server 3.6 should be upgraded to SEP 11.0 MR3 or later. SEP users running a version of Quarantine Server from SEP 11.x later than MR2 are not vulnerable. Reporting has replaced AMS2 as the recommended method of alerting. Symantec recommends that customers who are still using AMS2 switch to Reporting to manage alerts in their environments.
If the customer is unable to switch to Reporting immediately or upgrade to a non-vulnerable version then Symantec recommends that the customer either disable AMS2 as a temporary mitigation or completely uninstall AMS2.
As an additional mitigation, Symantec recommends blocking port 38292 in the corporate environment. This will effectively disable the alert service from sending or receiving messages.

As part of normal best practices, Symantec strongly recommends:
