Vulnerability Note VU#896220

Original Release Date: 2005-08-16 | Last Revised: 2005-09-08


A buffer overflow in Adobe Acrobat/Acrobat Reader may allow a remote attacker to execute arbitrary code or cause a denial-of-service condition


Adobe Acrobat is a suite of applications that allow users to manipulate PDF (Portable Document Format) files. A buffer within a core plug-in for Adobe Acrobat and Acrobat Reader can be overwritten using a specially-crafted PDF document.

For more information refer to Adobe Security Advisory 321644.


If a remote attacker can persuade a user to access a specially crafted PDF file, that attacker may be able to execute arbitrary code or crash the Adobe Acrobat/Acrobat Reader process.


Upgrade to unaffected version
Upgrade to unaffected versions of Adobe Acrobat and Acrobat Reader. For a list of unaffected versions please see Adobe Security Advisory 321644.

Do not accept PDF files from untrusted sources

Exploitation occurs by accessing a specially crafted PDF file. By only accessing PDF files from trusted or known sources, the chances of exploitation are reduced.
