Beware Excel Files Bearing Flash Vulnerabilities
Adobe has issued a security advisory about a vulnerability in current and past versions of Adobe Flash Player for all platforms that could enable an attacker to take control of an affected system. The vulnerability is reportedly being exploited in the wild via a Flash (.swf) file embedded in a Microsoft Excel (.xls) document delivered as an email attachment. Adobe expects to release a fix next week, but until then, be very careful of Excel files in email.
