Adobe Acrobat (Full Version) Javascript Parsing Flaw Lets Malicious PDF Files Execute Arbitrary Code
SecurityTracker Alert ID:  1006715
SecurityTracker URL:  http://securitytracker.com/id/1006715
CVE Reference:   CVE-2003-0284   (Links to External Site)
Updated:  Feb 29 2004
Original Entry Date:  May 7 2003
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): 5.0 - 5.0.5
Description:   A vulnerability was reported in the full version of Adobe Acrobat. A remote user can create malicious PDF files that will execute arbitrary code on the target user's system.

When the malicious PDF file is loaded by the target user's Acrobat, arbitrary code will be installed on the target user's system and will be executed the next time that Acrobat is loaded.

Adobe states that the free Acrobat Reader is not affected.

The vulnerability reportedly resides in the Javascript parsing engine, allowing a remote user's malicious PDF document to write code into the target user's Plug-ins folder. Appropriately formatted files in this folder are automatically installed and executed when Acrobat is launched.

This flaw is reportedly exploitable by a known virus that can replicate via PDF documents that are opened and then saved via Acrobat.

Impact:   A remote user can cause arbitrary code to be executed on a target user's computer.
Solution:   The vendor has released a patch for 5.0.5 and a fixed version (6.0):
