Adobe Macromedia Flash Player multiple remote code execution vulnerabilities

Number: AV06-031
Date: 13 September 2006

Purpose

The purpose of this advisory is to bring attention to multiple vulnerabilities that have been identified in Adobe Macromedia Flash Player.

Assessment

Critical vulnerabilities have been identified in Flash Player 8.0.24.0 and earlier versions that could allow an attacker who successfully exploits these vulnerabilities to take control of the affected system. A malicious SWF file must be loaded in Flash Player by the end user for an attacker to exploit these vulnerabilities.

The first flaw is due to input validation errors when handling overly long dynamically generated strings, which could be exploited by remote attackers to execute arbitrary commands via a malcious web page.

The second issue is due to an error within the "allowScriptAccess" option, which could be exploited by malicious web sites to bypass security restrictions and conduct cross domain scripting attacks.

The third vulnerability is due to an error in the way the ActiveX control is invoked by Office products, which could be exploited by attackers to execute arbitrary Flash code without user interaction when a malicious office document is opened.

Suggested action

DPS recommends that administrators test and upgrade to the newest version 9.0.16.0 at:
