Macromedia Flash Player Vulnerability

Macromedia Flash Player SWF File Handling Arbitrary Code Execution

Secunia Advisory: SA17430
Release Date: -- 2005-11-05

Critical: ------ Highly critical
Impact: -------- System access
Where: --------- From remote
Solution Status: Vendor Patch

Software:
Macromedia Flash Player 6.x
Macromedia Flash Player 7.x

Description:
eEye Digital Security has reported a vulnerability in Macromedia Flash Player, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to missing validation of the frame type identifier that is read from a SWF file. This value is used as an index in Flash.ocx to reference an array of function pointers. This can be exploited via a specially crafted SWF file to cause the index to reference memory that are under the attackers control, which causes Flash Player to use attacker supplied values as function pointers.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been reported in Flash Player version 7.0.19.0 and prior.

Solution:
Update to Flash Player 8 (8.0.22.0) or apply Flash Player 7 update (7.0.61.0 or 7.0.60.0).

Flash Player 8 download:
»www.macromedia.com/shockwave/dow···aveFlash

Flast Player 7 update:
»www.macromedia.com/go/d9c2fe33
More: »www.macromedia.com/devnet/securi···-07.html

Heads up everyone...

I used to know how to do this. It seems my brain isn't working today. How do I find out which version of the player I have. I'm pretty sure I updated to 8 when it came out but I would like to be sure. Thank you-Sith

Thanks for these very useful links,but ,like mrsplants,i'd like to know if it's better to uninstall or you just download the new version ? Or is it just the same?

Interesting foible
checking version in Firefox gave version 7 but checking in IE6 gave version 8 so needed to download new version.
Appears as though IE6 updated itself but not other browsers

For those who have any questions regarding Flash Player installation see Flash Player TechNote.

Previous versions of Macromedia Flash Player should be removed. Uninstall any previous version of Flash Player before using the standalone installer.

Hope that helps.

yes, it seems that while you can update both Flash player and the Shockwave player in Internet explorer on the macromedia.com site itself, you STILL need to do a seperate download to your pc in the case of updating the players in Firefox.

hmm, in firefox , the shockwave player updated fine, but i am having trouble installing the flash player. for some reason the installation is not extracting properly. it tells me "extracting to folder..", it goes to 100%, but then it just dissapears.(??)
no next prompt.

Macromedia recommends downloading the standalone installer, closing all open browsers, and removing previous Flash Player version (Windows Add/Remove Programs) before installing the version 8.

At least, that worked fine for me with both Firefox and IE.
