From remote

Impact:

System access

Solution Status:

Vendor Patch

CVE Reference(s):

Description


A vulnerability has been reported in Adobe Flash Player, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an error when parsing ActionScript that adds a custom function to the prototype of a predefined class. This results in incorrect interpretation of an object (i.e. object type confusion) when calling the custom function, which causes an invalid pointer to be dereferenced.

Successful exploitation allows execution of arbitrary code.

The vulnerability is reported in the following versions:
* Adobe Flash Player 10.2.153.1 and earlier versions for Windows, Macintosh, Linux, and Solaris
* Adobe Flash Player 10.2.154.25 and earlier for Chrome
* Adobe Flash Player 10.2.156.12 and earlier for Android

NOTE: The vulnerability is currently being actively exploited via Office Word documents (.doc) containing malicious Flash content.


Solution:
Update to Flash Player 10.2.159.1 and AIR 2.6.19140.

Perhaps U are not aware but Secunia prefer users not to ask question on their Vulnerability Information Sub forum.

That said, there is a patch available for this item. Just follow these steps & your question will not apply.

UPDATING STANDALONE ADOBE FLASH

Uninstall Flash using the uninstaller here:

http://kb2.adobe.com/cps/141/tn_14157.html SAVE IT TO DESKTOP

Before using the uninstaller COMPLETELY EXIT (just closing them is not sufficient) all these:

a. All Browsers.
b. Windows Messenger.
c. Incredimail.
d. Adobe Free Reader.
e. PSI unless using Version 2.

1. Download & SAVE these to desktop.
http://fpdownload.adobe.com/get/flashplayer/curren...

& then here if U have any Gecko based browsers.

http://fpdownload.adobe.com/get/flashplayer/curren...

2. The installer will appear on the desk top. THE IMPORTANT BIT - Before agreeing to install check these programmes are completely shut down (use the Task Manager if necessary to COMPLETELY EXIT the running process):
a. All Browsers.
b. Windows Messenger.
c. Incredimail.
d. All Adobe Products.
e. PSI - Unless using version 2


3. The new install will then remove all old files during the update process.
4. Complete a PSI rescan & all should be in order.
5. Delete the Flash installer file from the desktop.
