Adobe Flash 10.1.85.3 contains a vulnerability that can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Adobe Flash 10.1.85.3 and earlier versions as well as 10.2.161.23 and earlier 10.2 preview versions contain a vulnerability that can result in memory corruption, which can allow arbitrary code execution. Any application that supports Flash or provides its own runtime may be vulnerable. This vulnerability is being exploited in the wild.
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), PDF file, Microsoft Office document, or any other document that supports embedded SWF content, an attacker may be able to execute arbitrary code.
Apply an update
This issue is addressed in Adobe Flash 10.1.102.64. More details are available in Adobe Security Bulletin APSB10-26. Adobe Reader and Acrobat 9.4.1 address this issue. More details are available in APSB10-28. For other affected products, please see Adobe Security Bulletin APSA10-05 and consider the following workarounds:
Disable Flash in your web browser
Disable Flash or selectively enable Flash content as described in Securing Your Web Browser.
Disable Flash and 3D & Multimedia support in Adobe Reader 9
Flash and 3D & Multimedia support are implemented as plug-in libraries in Adobe Reader. Disabling Flash in Adobe Reader will only mitigate attacks that use an SWF embedded in a PDF file. Disabling 3D & Multimedia support does not directly address the vulnerability, but it does provide additional mitigation and results not in a crash but in a more user-friendly error message.
To disable Flash and 3D & Multimedia support in Adobe Reader 9 on Microsoft Windows, delete or rename these files:
"%ProgramFiles%\Adobe\Reader 9.0\Reader\authplay.dll"
"%ProgramFiles%\Adobe\Reader 9.0\Reader\rt3d.dll"
For Apple Mac OS X, delete or rename these files:
"/Applications/Adobe Reader 9/Adobe Reader.app/Contents/Frameworks/AuthPlayLib.bundle"
"/Applications/Adobe Reader 9/Adobe Reader.app/Contents/Frameworks/Adobe3D.framework"
For GNU/Linux, delete or rename these files (locations may vary among distributions):
"/opt/Adobe/Reader9/Reader/intellinux/lib/libauthplay.so"
"/opt/Adobe/Reader9/Reader/intellinux/lib/librt3d.so"
File locations may be different for Adobe Acrobat or other Adobe products that include Flash and 3D & Multimedia support. Disabling these plug-ins will reduce functionality and will not protect against SWF files hosted on websites. Depending on the update schedule for products other than Flash Player, consider leaving Flash and 3D & Multimedia support disabled unless they are absolutely required.
Remove Flash
Adobe has provided a TechNote with utilities for uninstalling the Flash Player plug-in and ActiveX control on Windows and Mac OS X systems. Removing these components can mitigate the web browser attack vector for this vulnerability. Note that this will not remove the instances of Flash Player that are installed with Adobe Reader or other Adobe products.
Disable JavaScript in Adobe Reader and Acrobat
Disabling JavaScript can help mitigate some techniques that use Adobe Reader as an attack vector.
To disable JavaScript in Adobe Reader:
Edit
menu.Preferences...
option.JavaScript
section.Enable Acrobat JavaScript
checkbox.Prevent Internet Explorer from automatically opening PDF documents
The installer for Adobe Reader and Acrobat configures Internet Explorer to automatically open PDF files without any user interaction. This behavior can be reverted to the safer option of prompting the user by importing the following as a .REG file:
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\AcroExch.Document.7]
"EditFlags"=hex:00,00,00,00
Disable the displaying of PDF documents in the web browser
Preventing PDF documents from opening inside a web browser reduces the attack surface. If this workaround is applied to updated versions of Adobe Reader and Acrobat, it may protect against future vulnerabilities.
To prevent PDF documents from automatically opening in a web browser with Adobe Reader:
Edit
menu.Preferences...
option.Internet
section.Display PDF in browser
checkbox.298081
