(AP) - Oracle says it has released a fix for the flaw in its Java software that raised an alarm from the U.S. Department of Homeland Security last week. Late Thursday, the federal agency recommended that Internet users disable Java software in Web browsers to avoid potential hacking attacks. Java allows programs to run within websites and powers some advertising networks. Users who disable Java may not be able to see portions of websites that display real-time data such as stock tickers, news, weather updates and ads. Oracle says the patch was released Sunday. The company recommends that users update Java immediately. The patch sets Java's default security level to "high" so it prompts users and gives them a chance to decline malicious software before it loads onto their computers.
