Java which is from the US based software company Oracle has today released an emergency patch for Java in an effort to fix a flaw that happens during installation on Windows platforms. 

This vulnerability could cause an exploitation of a critical vulnerability allowing someone to manipulate a user into going to a website containing malicious code and files and downloading them to the user’s system before Java gets installed.   This applies to Java versions 6, 7 or 8. 

Basically this site appears to be a Java site even though a user may be nowhere near the actual Java site.

Because the exposure exists only during the installation process, users need not upgrade existing Java installations to address the vulnerability. However, Java users who have downloaded any old version of Java prior to 6u113, 7u97 or 8u73, should discard these old downloads and replace them with 6u113, 7u97 or 8u73 or later.

Java home users should visit www.Java.com to check that they are using the most recent version of Java.
