ZDI-08-072: Adobe Acrobat PDF Javascript printf Stack Overflow 
Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-08-072
November 4, 2008

-- CVE ID:
CVE-2008-2992

-- Affected Vendors:
Adobe

-- 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
details can be found at:
