MS-ISAC CYBER SECURITY ADVISORY NUMBER:
Multiple Vulnerabilities in Adobe Flash Player Could Allow Remote Code Execution (APSB14-07)
Multiple vulnerabilities have been discovered in Adobe Flash Player that could allow an attacker to remotely take control of the affected system. Adobe Flash Player is a multimedia platform used to add animation and interactivity to web pages. Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.
At this time, these vulnerabilities are not publicly disclosed and there is no known proof-of-concept code available.
