Last week Apple updated OS X to version 10.9.3 and also released a version of iTunes which was updated again the following day after a problem was found for some users. Along with the OS X update, Safari was also updated to version 7.0.3.

This morning I see another update to Safari, this time 7.0.4 with the advice being, "contains improvements to security".

The information contained in the Knowledge Base document (HT6254) for the update identifies several developers and groups who had contributed to the discovery of vulnerabilities that were fixed.
