Who is Vulnerable?
Vulnerability Description	Symantec Alert management System 2 (AMS2) is a package used by various Symantec solutions such as System Center, AntiVirus Server, and AntiVirus Central Quarantine Server. AMS2 starts multiple services on the system that run with System account privileges, by default. A stack buffer overflow vulnerability has been discovered in Symantec Alert Management System. The vulnerability is caused by code which copies a user supplied string into a stack buffer without proper bounds checks. The vulnerable code (contained in AMSLIB.dll) handles data sent to the msgsys.exe process which listens on port TCP/38292 by default. A remote attacker could exploit this issue by sending a specially crafted packet to the affected service. Successful exploitation could result in arbitrary code execution on the target system.
