. This critical security update for Windows XP addresses vulnerabilities in the Macromedia Flash Player from Adobe that could allow remote code execution.Several remote code execution vulnerabilities exist in Macromedia Flash Player from Adobe because of the way that it handles Flash Animation (SWF) files. An attacker could exploit these vulnerabilities by constructing a specially crafted Flash Animation (SWF) file that could potentially allow remote code execution if a user visited a Web site containing the specially crafted SWF file. The specially crafted SWF file could also be sent as an e-mail attachment. A user would only be at risk if opening this e-mail attachment. An attacker who successfully exploited these vulnerabilities could take complete control of an affected system.
