Symantec has released detection for any potential exploits, and has provided details on how to check if software is vulnerable so that a patch can be applied, here. A Secunia alert on the issue is here.

According to a report in The Register (here), Norton 2006 users have also been experiencing problems with their subscriptions, with false messages warning of imminent expiry of their licence to access updates. A fix for the problem is thought to be available (here), and users may be able to upgrade to the 2007 line, which is not thought to be affected by the problem.
