The headaches surrounding the most recent Australia Homeland Security warning surrounding Java 7 are not going away for Oracle and users of Java. This leaves computer users scratching their heads on what they should do today to protect their computers and limit any risk to corporate network environments.

Since the original warning issued by Australia Homeland Security a few weeks ago, Oracle released an update to Java which did fix one component in the program. However, even after the new security fix to patch Java 7 from this massive security vulnerability, the U.S. Department of Homeland Security has reiterated its warning that Java still poses risks.

Java fault-finder Adam Gowdiak discovered another vulnerability with the Java 7 update 11 and advices Oracle they must “bring security research to the new level.” The Oracle’s most recent update shows vulnerability to hackers which may affect users without their knowledge leaving their computers or mobile devices open to a potential hacking attack.
