ActionScript in Adobe Flash Player 9.0.124.0 and earlier does not require user interaction in conjunction with (1) the FileReference.browse operation in the FileReference upload API or (2) the FileReference.download operation in the FileReference download API, which allows remote attackers to create a browse dialog box, and possibly have unspecified other impact, via an SWF file.

The System.setClipboard method in ActionScript in Adobe Flash Player 9.0.124.0 and earlier allows remote attackers to populate the clipboard with a URL that is difficult to delete and does not require user interaction to populate the clipboard, as exploited in the wild in August 2008.

Adobe Flash Player 9.0.115.0 and earlier, and 8.0.39.0 and earlier, allows remote attackers to execute arbitrary code via an SWF file with a modified DeclareFunction2 Actionscript tag, which prevents an object from being instantiated properly.

ActionScript 3 (AS3) in Adobe Flash Player 9.0.47.0, and other versions and other 9.0.124.0 and earlier versions, allows remote attackers to bypass the Security Sandbox Model, obtain sensitive information, and port scan arbitrary hosts via a Flash (SWF) movie that specifies a connection to make, then uses timing discrepancies from the SecurityErrorEvent error to determine whether a port is open or not. NOTE: 9.0.115.0 introduces support for a workaround, but does not fix the vulnerability.

Cross-site scripting (XSS) vulnerability in Jelsoft vBulletin allows remote attackers to inject arbitrary web script or HTML via an SWF file that uses ActionScript to trigger execution of JavaScript.

CRLF injection vulnerability in Adobe Flash Player plugin 9.0.16 and earlier for Windows, 7.0.63 and earlier for Linux, 7.x before 7.0 r67 for Solaris, and before 9.0.28.0 for Mac OS X, allows remote attackers to modify HTTP headers of client requests and conduct HTTP Request Splitting attacks via CRLF sequences in arguments to the ActionScript functions (1) XML.addRequestHeader and (2) XML.contentType. NOTE: the flexibility of the attack varies depending on the type of web browser being used.

Cross-site scripting (XSS) vulnerability in XMB Forum 1.9.5 allows remote attackers to inject arbitrary web script or HTML by uploading a Flash (.SWF) video that contains a getURL function call, which causes the video to be rendered without disabling ActionScript.

jscript.dll in Microsoft Internet Explorer 6.0 SP1 and earlier allows remote attackers to cause a denial of service (application crash) via a Shockwave Flash object that contains ActionScript code that calls VBScript, which in turn calls the Javascript document.write function, which triggers a null dereference.

Macromedia Flash plugin (1) Flash.ocx 7.0.19.0 (Windows) and earlier and (2) libflashplayer.so before 7.0.25.0 (Unix) allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via parameters to the ActionDefineFunction ActionScript call in a SWF file, which causes an improper memory access condition, a different vulnerability than CVE-2005-2628.
