Rafel Ivgi has reported a vulnerability in Adobe Acrobat Reader, which potentially can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error within the "pdf.ocx" ActiveX component supplied with Adobe Acrobat Reader. This can e.g. be exploited via a malicious website using a specially crafted URL to potentially execute arbitrary code.

Example:
http://[host]/[directory]/[existing_pdf].pdf%00[long_string]

NOTE: This only works on servers, which truncate the URL before the "%00" sequence (e.g. IIS and Netscape Enterprise).

The vulnerability has been reported in version 5.0.5. Other versions may also be affected.

Solution
The vendor has stated that this issue was fixed in Adobe Acrobat Reader 6.0.2. However, it has been reported that the issue might not have been completely fixed and still can be used to cause a Denial of Service (DoS).
