Preventing those attacks from affecting Firefox users would mean blacklisting the latest version of the Java plug-in for Mac, which would leave them without the ability to use Java applications in Firefox. On Monday, security researchers from F-Secure announced that new Web-based attacks are exploiting a vulnerability in the latest Java version for Mac OS in order to install malware. However, blocking Java on OS X might be trickier than on Windows, because Apple is usually months behind Oracle in delivering Java patches. Mozilla is also considering adding a blocklist entry for the Java plug-in on OS X. The latest versions of Java for Windows are Java 6 Update 31 and Java 7 Update 3. "Mozilla strongly encourages anyone who requires the JDK and JRE to update to the current version as soon as possible on all platforms," Needham said. In October 2009, Mozilla decided to add Microsoft's Windows Presentation Foundation (WPF) plug-in to the Firefox blocklist after Microsoft revealed that it had a vulnerability. The Firefox blocklist has rarely been used to disable plug-ins from big software vendors like Oracle, but precedents do exist. However, users retain the choice of preventing those plug-ins from being disabled. Unlike Google's Chrome browser, which has a feature specifically aimed at disabling outdated plug-ins, Firefox relies on Mozilla developers deciding which plug-ins pose a risk to users. Needham did not specify the vulnerability being actively exploited, but security companies have warned during the past couple of weeks that exploits for the CVE-2010-0507 Java vulnerability were being used in widespread attacks and have been incorporated into the popular Blackhole exploit toolkit. "To mitigate this risk, we have added affected versions of the Java plugin for Windows (Version 6 Update 30 and below as well as Version 7 Update 2 and below) to Firefox's blocklist." If you are not satisfied with the current Firefox version, or it simply is not working right now, there are alternative browsers that you can use to browse the web."This vulnerability - present in the older versions of the JDK and JRE - is actively being exploited, and is a potential risk to users," Needham said. impacted than those who operate with administrative user rights. Use the latest version of another browser. version of the web browser used on Android based mobile devices.
