Apple has updated the Xprotect anti-malware system built into OS X. The update prevents using the Java plug-in up to the current version 7 update 11 (22.214.171.124), as MacGeneration noticed.
When running Java content, Safari refers to the blockage and recommends obtaining a newer version from Oracle's website - there is currently no update available for download. As a new minimum requirement, Xprotect lists version 126.96.36.199.
At the beginning of January, a dangerous vulnerability in Java became public, as a result of which Apple also blocked the Java plug-in in version 7 update 10 - a few days later, Oracle finally released a patch with version 7 update 11. Last Tuesday, a security researcher pointed out that bypasses the newly introduced protection function of the Java plug-in. (lbe)
