Oracle has just released Security Alert CVE-2012-4681 to address 3 distinct but related vulnerabilities and one security-in-depth issue affecting Java running in desktop browsers. These vulnerabilities are: CVE-2012-4681, CVE-2012-1682, CVE-2012-3136, and CVE-2012-0547. These vulnerabilities are not applicable to standalone Java desktop applications or Java running on servers, i.e. these vulnerabilities do not affect any Oracle server based software.
Apparently, Oracle knew about the problem for months, and did nothing to resolve it. Who says researchers are security Security Explorations, have warned that indicate the company several months ago.
To check the version you have installed should re-enable Java in the browser, if the disabled are as indicated, and access Java test page.
Due to the high severity of these vulnerabilities, Oracle recommends that customers apply this Security Alert as soon as possible. Furthermore, note that the technical details of these vulnerabilities are widely available on the Internet and Oracle has received external reports that these vulnerabilities are being actively exploited in the wild.
