Who is Vulnerable?
Vulnerability Description	Symantec Antivirus Corporate Edition and Symantec Client Security are applications designed to protect organizations from the threat of viruses, malware, and intrusion attempts. Both applications can be deployed in an enterprise network environment, and they both support an anti-virus scanning mechanism, a firewall with centralized management, and an automatic signature update mechanism. There exists a stack buffer overflow vulnerability in the Real-Time Scan Service component of various Symantec Antivirus products. The flaw exists due to insufficient verification of user input processed by the service Log Forwarding component. In a case of an unsuccessful code execution attempt, the target seems to enter a corrupted state. Restarting or killing the process via common methods seems to be impossible. The functionality is restored upon restarting the target system. In an improbable case where code injection is successful, the flow of the process is diverted to the injected code and the attacker may execute arbitrary code on the target system. In such a case, the behaviour of the target host is dependent on the intention of the injected code. Any code executed will be within the privileges of the current service process, which is System by default.
