The Real-Time scanner (RTVScan) component of Symantec Antivirus Corporate Edition provides notification and logging services for the product. One function of RTVScan is to display a notification window with information about a threat found on the system, if the program is configured to use that option. Ali Rahbar notified Symantec that an unprivileged user could potentially attack this window with specially crafted code, and gain SYSTEM level privileges on their local system. The user could then run code of their choice on their local system.
Symantec engineers have verified that the issue exists in the versions of Symantec AntiVirus Corporate Edition listed in the table above. Our investigation showed that the potential attack is limited to the local user, and that the elevation of privilege is limited to the userís own system.
Symantec is not aware of any customers impacted by this issue, or of any attempts to exploit the issue.
As a part of normal best practices, users should keep vendor-supplied patches for all application software and operating systems up-to-date. Symantec recommends any affected customers update their product immediately to protect against potential attempts to exploit this issue.
In a managed environment, administrators can disable Notification Message (alert) window, and lock the notification option to prevent users from re-enabling the Notification Message window.
Symantec recommends any affected customers update their product to protect against potential attempts to exploit this issue. As part of normal best practices, Symantec recommends the following:
- Run under the principle of least privilege to limit the impact of exploits.
- Keep all operating systems and applications updated with the latest vendor patches.
- Follow a multi-layered approach to security. Run both firewall and antivirus software to provide multiple points of detection and protection from inbound and outbound threats.
- Use network intrusion detection systems to monitor network traffic for signs of anomalous activity. This may aid in detection of attacks related to exploitation of vulnerabilities.
