ZDI-11-299 : Adobe Reader  PICT Parsing Remote Code Execution Vulnerability
http://www.zerodayinitiative.com/advisories/ZDI-11-299
October 26, 2011

-- CVE ID:
CVE-2011-2435

-- CVSS:
7.5, AV:N/AC:L/Au:N/C:P/I:P/A:P

-- Affected Vendors:

Adobe



-- Affected Products:

Adobe Reader



-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Adobe Reader. 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 within the Adobe 2D.x3d PICT image parsing
routines. When Adobe Reader parses an PICT image it uses a static buffer
to store certain image header values. Due to insufficient checks for the
end of the buffer it is possible to write outside the stack buffer. The
resulting stack overflow could result in remote code execution under the
context of the current user.

-- Vendor Response:

Adobe has issued an update to correct this vulnerability. More details
