Bugs in Oracle's Java software, which runs on almost every operating system, including Microsoft's Windows and Apple's OS X, could render affected computers vulnerable to identity theft and other cybercrimes.
Oracle released an update Sunday after officials from the U.S. Department of Homeland Security urged PC users to disable Java version 7 in their computers which could let hackers steal credit card numbers, passwords, banking credentials and other types of sensitive personal information.
Reports show hackers exploited a loophole in a version of Java used with Internet browsers like Firefox and Internet Explorer.
Users are encouraged to download the update. Although the bug only affects Java 7, some security experts say users should disable Java on their computers.
Reports show Apple addressed the issue earlier by disabling Java 7 because all systems running the software failed to pass tests launched through Apple's anti-malware system already built into OS X.
Java runs on most computers, smartphones, webcams, Blu-ray players and other devices.
A December 2012 survey from security software maker Kapersky Lab shows "Java was the most frequently exploited software by cybercriminals during , with Adobe Reader and Adobe Flash Player ranking in the second and third places, respectively."
