Yesterday, Adobe announced that a zero-day exploit exists in Flash 10.0.45.2 and earlier, as well as Adobe Reader and Acrobat 9.x. The company website explains:
…(CVE-2010-1297) could cause a crash and potentially allow an attacker to take control of the affected system. There are reports that this vulnerability is being actively exploited in the wild against both Adobe Flash Player, and Adobe Reader and Acrobat.
The zero-day exploit, without question, is the mother of all vulnerabilities. A recent report put the black market price tag of a good zero-day exploit — on that can be widely distributed — at just north of $50,000. Governments and private security firms have been rumored to pay more than quadruple that figure on the “white market” if the vulnerability is severe enough. We’ve got the complete security bulletin, with mitigation instructions, queued up for you after the bounce.
