The exploit has been assigned a Common Vulnerabilities and Exposures reference (CVE-2013-0422) see http://cve.mitre.org.
At present, the only workaround available are :
- Disable Java entirely
- If you don’t need Java, remove it from the system entirely
Cyberkryption advises to check to see if Java is installed on your machine as it is often installed by third party programs that require it, on Windows systems this can be done in the Control Panel.
There is a guide to disabling java in your web browser for PC & Mac based systems here. For Linux based systems, Cyberkryption recommends you check your distributions forums.
