Apple shipped a new Flash Player plugin (10.0.45.2) in the Mac OS X patch bundle but that version became outdated on June 10th when Adobe shipped Flash Player 10.1.53.64. Adobe recommends users verify they are using the latest, most secure version of Flash Player available for download from https://www.adobe.com/go/getflashplayer.com. At least one of those flaws have been exploited on the Windows platform. Earlier today Apple released security update 2010-004 / Mac. OS X v10.6.4.
