ZDI-08-072: Adobe Acrobat PDF Javascript printf Stack Overflow



November 4, 2008

-- CVE ID:


-- Affected Vendors:


-- Affected Products:

Adobe Acrobat

-- Vulnerability Details:

This vulnerability allows remote attackers to execute arbitrary code on

vulnerable installations of Adobe Acrobat. User interaction is required

to exploit this vulnerability in that the target must visit a malicious

page or open a malicious file.

The specific flaw exists in the handling of embedded Javascript code

when opening a PDF. Adobe Acrobat has defined it's own set of

Javascript functions that can be used in a PDF file. Due to improper

parameter checking to one of these functions arbitrary memory can be

over-written leading to remote code execution. If successfully

exploited remote control of the target system can be gained with the

credentials of the logged in user.

-- Vendor Response:

Adobe has issued an update to correct this vulnerability. More
