An in-the-wild exploit targets Silverlight, a web plugin used by popular sites such as Netflix. The flaw, which exists in versions prior to 5.1.20125.0, allows attackers to execute arbitrary code on affected systems without any user interaction. Microsoft patched the flaw (CVE-2013-0074) on March 12, 2013. Netflix, which has 40 million subscribers, requires Silverlight for its paid streaming video service. Those that do not have the plugin yet will be redirected to download the latest (and safe) version.”]
