A vulnerability in Adobe Flash Player could allow an unauthenticated, remote attacker to execute arbitrary code.
The vulnerability is due to a variable unspecified type confusion error in the affected software. An unauthenticated, remote attacker could exploit this vulnerability by convincing a user to visit a malicious web page that contains crafted Flash content. A successful exploit could allow the attacker to execute arbitrary code on the system with the privileges of the user.
Adobe confirmed the vulnerability and released updated software.
