Signature Detail

APP: Symantec Alert Management System Pin Number Stack Buffer Overflow

This signature detects attempts to exploit a known stack buffer overflow vulnerability in Symantec's Alert Management System. It is caused by code that copies a user supplied Pin Number into a stack buffer without prior validation of its size. The vulnerable code (contained in pagehndl.dll) handles data sent from the msgsys.exe process, which listens on port TCP/38292 by default. A remote unauthenticated attacker can exploit this by sending specially crafted input to the affected service. A successful attack can result in arbitrary code execution in the SYSTEM context

Extended Description

Symantec Intel Alert Management System (AMS2) is prone to multiple remote buffer-overflow vulnerabilities. AMS2 is used in multiple Symantec products including Symantec AntiVirus Corporate Edition Server (SAVCE), Symantec System Center (SSC), and Symantec Quarantine Server. Attackers can exploit these issues to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.
