Adobe Reader is a program for viewing Portable Document Format (PDF) documents. Acrobat is the program used to create such documents. More information is available at the following URLs.
Exploitation of this vulnerability would allow an attacker to execute arbitrary code as the current user. In order to exploit this vulnerability, an attacker would have to convince the targeted user to open a maliciously constructed file. This file could be sent directly to the targeted user or linked from a website.
Insufficient error checking is performed on the input which allows, among other things, attacker-supplied data to be written to arbitrary offsets in memory, potentially resulting in arbitrary code execution.
iDefense has confirmed this vulnerability exists in Adobe Reader 8.1 on Windows XP SP2. It is likely that other Adobe products that handle PDF files, including previous versions of Adobe Reader, are also affected.
Adobe released version 8.1.2 of Adobe Reader and Acrobat to address this vulnerability. Although there is currently no update for version 7.0.9, Adobe reports it does plan to release one at a later date. For more information, visit the vendor's advisory at the following URL.
