Who is Vulnerable?
Vulnerability Description	The Symantec System Center includes an optional component called the Alert Management System (AMS2). The AMS2 starts multiple services on the system that include an alert handler service from Intel Corporation called the AMS2 Handler Manager Service (HNDLRSVC.EXE). A denial of service vulnerability has been reported in Symantec's Antivirus Intel Alert Handler service.

A remote attacker may exploit this issue by sending a crafted packet, containing a malicious size value, to the target service. Successful exploitation of this vulnerability would result in termination of the affected service, causing a denial of service condition.
