Description

Security researcher Gregory Fleischer reported a vulnerability in the way Mozilla indicates the origin of a document to the Java Embedding Plugin (JEP) that ships with Firefox on Mac OS X. This vulnerability could allow a malicious Java applet to bypass the same-origin policy and create arbitrary socket connections to other domains.

Workaround

Disable Java on Mac OS X until a version containing these fixes can be installed.
