Security analysts from Secure Network Operations notified Symantec of a potential issue with the NetDetect task that runs as a scheduled task as a part of Automatic LiveUpdate. If the system is configured as a multi-user system with privileged and non-privileged user access, a non-privileged user could potentially access and manipulate the Symantec Windows LiveUpdate GUI functionality to gain privileged system access.
NOTE: Neither of these potential issues could be used to deploy malware or result in remote access to a client system.
