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
