Java Security Alert

A security flaw that allows hackers and criminals to take control of computer workstations (desktop and laptop) has been reported and publicized.  Many Windows workstations are vulnerable, and it is easy to take advantage of the flaw.  The problem is in Java, which is developed and maintained by Sun (now owned by Oracle) and is installed to support browsers such as Internet Explorer and Mozilla Firefox.  All that's needed to infect a vulnerable computer is to visit a malicious web page.    

This flaw is rated as the highest possible vulnerability because most personal computer systems are set for the user to operate with administrative privileges, which gives the exploit full control of the workstation.

The vulnerability is present in Windows XP, Windows 7, Vista, Windows 98, Windows 2003, Windows 2000, Windows 2008 Server, Windows ME, Solaris SPARC, Solaris x86, Red Hat Linux, SUSE Linux, JDS.  It is not present in Apple's OS X.
