Consider immediately upgrading to Adobe Flash v10.1.Sharable Shortlink
SECURITY ALERT: The threat posed by the new zero-day (no warning, discovered by its active exploitation “in the wild” against users) flaw in all released versions of Adobe’s FLASH player — on all OS platforms — which can also be vectored through malicious PDF files to invoke FLASH, appears to be growing rapidly.
The bad guys are jumping on this one hard and fast.
Given that Adobe first learned of this problem a little after 10 AM Friday morning, June 4th, and that their quickest previous response to a similar threat was 15 days, the world may be waiting several weeks for a fix from Adobe.
Two things must be done for you to be safe:
• First: The good news is that the next major release of FLASH, version 10.1, is reportedly NOT vulnerable to this attack. Although v10.1′s release is not yet official, it has had seven release candidates and is currently very stable and usable. Therefore, anyone whose Internet usage might subject their machines to malicious FLASH content (depending upon how widely you surf the web) would be well advised to install the next major release of Adobe’s FLASH player, version 10.1, immediately. You can find additional information, and everything you’ll need at the following Abode Labs link:
• Second: (Windows ONLY) Both Adobe’s Reader and Acrobat contain their own built-in and equally vulnerable copies of FLASH in a file called “authplay.dll” (and most people have Adobe’s free Reader installed.) This allows PDF documents to contain and “play” embedded FLASH content — even though only malicious hackers ever do that. If by any chance you are still using version 8 of Reader or Acrobat, you are safe. But any 9.x and later versions are vulnerable. Therefore, the best thing to do would be to rename any copies of “authplay.dll” on your system to “authplay.xxx” so that your system won’t be able to find them. Once new versions of Reader and Acrobat are available they will bring a repaired copy of “authplay.dll” and all will be fine (at least until the next vulnerability is found). The “authplay.dll”s are typically found at:
C:\Program Files\Adobe\Reader 9.0\Reader\authplay.dll for Adobe Reader or
C:\Program Files\Adobe\Acrobat 9.0\Acrobat\authplay.dll for Acrobat.
You may also wish to search your system drive for any files of that name and rename them. Adobe’s vulnerability advisory is available here:
