Adobe issues out-of-band software update to fix dangerous security flaws in Flash Player products. One of the bugs, a cross-site scripting flaw, is being exploited in the wild in targeted attacks. Patches are available for versions of Flash on Windows, Mac, Linux, Solaris and Android operating systems. Windows users who browse the Web with anything other than Internet Explorer will need to apply the update twice, once using IE and again with the other browser (Google Chrome users should already have the latest version of Flash)”]
