Adobe Reader and Acrobat contains multiple buffer overflow vulnerabilities. Successful exploitation of this vulnerability may allow an attacker to execute code.
Adobe Acrobat Reader is software designed to view Portable Document Format (PDF) files. Adobe also distributes the Adobe Acrobat Plug-In to allow users to view PDF files inside of a web browser.
Per iDefense Advisory 02.08.08:
By convincing a user to open a specially-crafted PDF file, a remote, unauthenticated attacker may be able to execute arbitrary code. This can happen in several ways, such as opening an email attachment or viewing a web page.
According to the information in Adobe Security bulletin APSB08-13, users with version 8 of Adobe Reader or Acrobat should upgrade to version 8.1.2. Users running version 7 of Adobe Reader or Acrobat should upgrade to version 7.1.0. This issue was intially address for version 8 of Adobe Reader and Acrobat in Adobe Security advisory APSA08-01.
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
Do not open untrusted PDF files
Do not open unfamiliar or unexpected PDF attachments. Users can convert PDF documents to text by using the Adobe Online Conversion Tools site. See the Online Conversion Tools FAQ for information about this service. This workaround will not mitigate all attack vectors.
