Adobe Flash Player contains a vulnerability in the ActionScript 3 ByteArray class, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Adobe Flash Player versions 9.0 through version 18.0.0.194 contain a use-after-free vulnerability in the AS3 ByteArray class. This can allow attacker-controlled memory corruption. Exploit code for this vulnerability is publicly available.
An attacker can execute arbitrary code in the context of the user running Flash Player. Attacks typically involve enticing a user to visit a web site containing specially-crafted Flash content, or to open a specially-crafted Microsoft Office document.
Apply an update

Do not run untrusted Flash content
To defend against this and other, as yet unknown vulnerabilities, disable Flash in your browser or enable Click-to-Play features. Adobe has also provided instructions for how to uninstall Flash on Windows and Mac platforms.
Use the Microsoft Enhanced Mitigation Experience Toolkit
The Microsoft Enhanced Mitigation Experience Toolkit (EMET) can be used to help prevent exploitation of this vulnerability. In particular, Attack Surface Reduction (ASR) can be configured to help restrict Microsoft Office and Internet Explorer from loading the Flash ActiveX control.
