Hopefully an out-of-band patch will emerge sooner than the anticipated mid-September timeframe from Sun/Oracle. Below are approaches to stay protected until a patch arrives:
1. AVOIDANCE — Stay as safe as possible with respect to email, websites, Facebook, etc … Stay on mainstream sites and avoid anything suspicious. An ounce of prevention is worth a pound of cure.
2. AV PROTECTION — Most AV products offer exploit protection fairly soon as they emerge. Below is an example from Trend and other vendors have also recently added protection. AV protection helps, although it may not always be 100%
3. DISABLE JAVA — As noted in this article disabling Java is difficult for IE and it can help in cases where there are no business requirements to use Java
When the patch emerges, it will offer the best form of protection and should be quickly installed
