MacRumors is bringing attention to a security issue that could affect Mac users. Java SE 7 Update 6, the most recent version of Oracle's Java, contains a zero day flaw that could allow the installation of executable code on your Mac if you visit a compromised web site.

The problem is specific to Oracle's Java SE 7 updates 0 through 6. Apple currently delivers Macs with Java SE 6, the previous version of Java. So, although many sites are reporting this as a security issue for Macs, it's only a security issue if you manually updated to the most recent version of Java hosted on the Oracle site.
To determine which version of Java is installed on your Mac, do the following:
- Launch Java Preferences, located at /Applications/Utilities.
- Select the General tab.
- The version(s) of Java installed on your Mac will be listed. You may have more than one version installed, such as a 32-bit version and a 64-bit version. Make sure none of them say Java SE 7, with a version number of 0 through 6.
- If you do see Java SE 7 listed, remove the check mark from its box to turn that version of Java off.
